the old Licas or even now kodamatics or Polaroids since digital has obsoleted every camera over 5 years old..

Look for an old TLR like a Rolleicord. If you can find a Speed Graphic by Graflex, Even a good Leica rangefinder would be good.

Personally I would suggest a Polaroid camera that takes 600 film. Even though it is out of production if you buy a whole heap of the film bulk you can have maybe 100 shots to store in your fridge until the time comes to use them. If your not prepared to spend that much all in one hit get a Kodak Box Brownie that takes 120 film as they are pretty old, cheap and 120 film is a lot cheaper and easier to develop than the other film types in other Brownies. Another option is to buy a new camera, like a toy camera. I have a Holga which is made out of plastic and takes 120 film but you can get amazing results that cant be reproduced with photoshop. Check out http://www.lomography.com/ for more info. There’s quite a lot of cameras on offer there from cheap to very expensive. The community is great to get into and there are many ways to create unique images with these cameras

An old Rolleicord is an excellent camera. Not only is it a physical brick that has been around since God knows when, the optics are exceptional and they simply make good pictures (if you know how to use one). Twin Lens Reflex (TLR) cameras are fun to use, I have three of them and have a blast using them. Other old TLRs that will be nice are the Minolta Autocord, older Yashica models, and some old Zeiss models.

Make sure, however, of the condition. If an older camera like that has been sitting around for a while, chances are that the shutters are sticky and either will not work or will be very slow. I just bought an old Rolleicord that had a stick shutter and it is now being CLAed.

For a guarantee for one that works, look up http://www.keh.com and call about them.
