Is it worth selling mu 5 year old D70 camera (in good working condition) and buying this model?

It really depends on the quality of the dog house. If it's been kept in good condition and it can be used safely for your dog, then I say go for it. A new one costs around $80, so the price your neighbor is selling it should be much lower.

It's impossible to appraise the value remotely, sorry.

There are too many variables.

1. Even though it's about 80 years old, age doesn't equal valuable.

2. It's by Kodak, so an awful lot of them were made. It really isn't all that rare unless it has a noteworthy provenance.

3. Condition is everything, and the examples I see a few times a year vary from scrap to immaculate and fully functional. Most tend to be closer to the scrap level.

4. 116 film is no longer available, so it's no longer a usable model, limiting it's appeal.

5. It wasn't a historically noteworthy or innovative model, so is only really of interest to Kodak collectors, and serious collectors will often already have an A-116.

6. Price will depend upon where in the world the camera is located. It's not usually a high value model so buyers will not usually pay the high charges for insured trackable international shipping, especially if it's from the USA where non-domestic shipping rates are ridiculously overpriced.

7. Worldwide, most economies still lack confidence. Far fewer folks are paying for luxuries like collectibles for now. Prices will be a lot better when things pick up again.

8. Ultimately, it's only worth what someone will pay on the day that you sell it. Sounds obvious, but it's basically down to luck. If you happen to attract competing collectors on a specialist website then there's more chance of someone paying more than it's really worth.

Typically though, in the UK it will sell for anywhere from a few £ up to about £50-ish on a really good day for an exceptionally good example. If there's a bidding war with competing buyers then it may fetch £80-£100.

The HP Photosmart M537 is a 3-year old camera that was $100 when new. Yours is defective by your own admission and you want to sell it for "top dollar" to some poor soul? In its present condition, it's worth about $3 for parts. Even if the zoom worked, it would only be worth $20.

This machine is made by Ricoh and the same as a model Aficio 220. Pretty old and not worth much. If it runs and makes nice copies then $300 to $400. If it does not work or makes poor copies then next to nothing. I specialize in buying/selling used refurbished copiers and am very familiar with this model.
Good Luck and Thank You for using Fixya.

A ten year old mower that probably cost about $1500.00 at least twn years ago that has not been taken care of is not worth much.

John Deere is a good name as in Kohler. How much is it worth? It is currently worth what you paid for it, you just made it worth that much.

Is it a twin lens reflex? Very boxy, with two lenses on the front, one above the other? Some on them still sell for good $$ on Ebay, depending on the model and the condition. Clean in good working order can fetch $900 on Ebay. If knobs won't turn easily, and it needs to be cleaned and re-oiled, Somewhat less. But yes, its worth something, depending on model and condition. Its hard to give you anything more that that without knowing more.

On a 90 model the condition is every thing and the mileage is of little concern unless its more than 200 thou but the good run good looks and every thing working is worth more on this 20 year old CLUNKER The speedometer out of a junk truck is puickest and easyest. Hope you can find a yard that hadnt crushed em all as the metal in your truck was worth more than you can sell it for running just a few years ago and its still worth almost $300 on the metal scales right now. Government thought the cars program will give you $3500 towrds a new car or truck just to get it off the road so they can put it to sleep forever

Possibly not worth repairing.
You may have ruined the internal parts from over-voltage.
Any thing has a value to the owner, thus it is up to the owner as to how much he is willing to pay on repairs to fix the item. This applies to cameras of any kind, cars, houses, and so on.

I would suggest to look up the value that your camera has been selling for (on a site such as Ebay). How old is it? If it is over a couple years, the value may not outweigh the cost to repair. That will depend on the condition and other factors.

If the internal parts have been burned out, then the cost to replace a main board ,probably what you need, may be far more than what you want to pay. Since this is a 6.3 mpxl. camera, I would guess it is over two years old, and will not bring more than $100.00 if sold in good condition with all the things it had when new.
A suggestion is to sell this camera as parts on a site like Ebay, and get what you can. You may choose to sell all or just the camera.

if you intrested to sell the camera tell me how much u want otherwise lcd is available see www.omaxphoto.com.it mifht be something wrong with display back portion it has to be cheaked by an expert

I would take it to a specialist dealer.
It's probably not really old enough to be considered highly collectable, but it is collectable. Especially if you have any of the original documentation, instruction manual, bill of sale and so on. 37 years is a reasonable age and that puts it in the first of the modern style slr group. I would avoid any High Street chain or department store. Half the people who work in those outlets won't have a clue what it is unles it has an LCD on the back. Look for an independent long established shop.

Another long shot would be to search eBay but putting in the full model number and see if anyone has sold or is selling one

Hope this helps...
