Oh, camera bodies! You had me worried there for a minute with your headline! 
There are some great old cameras.... when you have a few hours to spare, start checking out http://camerapedia.wikia.com/wiki/Camerapedia
Here are few from my own collection...
This one will might "break the bank"... Only an estimated 600 to 1500 were made in 1960. I never thought I'd own one, but this was buried in a lot of cameras I bought on eBay, so I got it for far less than it's worth.
I just recently got a lens cap for this for $16 shipped! Seller didn't know what they had. It's extremely rare... I'd expect the lens cap alone to sell for $100+.
These too...
Sorry for the small image.
Don't even get me started on the folders, view cameras and such!
Some can be bought for little money... Russian SLR and rangefinder cameras and lenses for example.
Be sure to check any thrift stores in your area... I've picked up a number of great old cameras at one near me... Mostly 35mm film SLRs, rangefinders and P&S... Often for far less than eBay. There's a really nice chrome AE-1 Program with Canon FDn 50/1.8, 28/2.8 and 70-210/4 lenses over at my local Goodwill store right now, all in a bag with a few accessories, even spare battery and lens cleaning brush... the $100 they're asking is a little high and I already have a couple AE-1P anyway. I picked up a perfect black body Nikon FM2n there, with two lenses and a flash, for about $27. Also a Contarex Super B with three lenses, extra film back, and other accessories, all in 9+ condition, for under $40. More recently a Canon F1 (late) and shortly before that an FTb QL. And an Olympus XA, XA2, both with flashes, one in presentation case, and an Oly OM2.
Now, if you happent to see a Konilette (any of the early bakelite models, not the 1959 "Konilette 35") or....
Yeah. I'm addicted!
