As pros go digital, you will see all types of film camera being sold. Six months ago, I bought a Mamiya RZ Pro II camera, viewfinder, prism finder, two film backs, polaroid back, bellows, and power winder for $1900 including shipping. That's a steal.

For 35mm, you will see Canon 1V, Canon Eos3, Nikon F100, Nikon F5, etc. being sold for the sake of digital cameras. Find the system that you like and then shop for the lenses and cameras that you like. You will find plenty of used cameras on Ebay, BH Photo, KEH, etc. For used equipment I prefer to use KEH or BH Photo since they have a return policy.

Just recently I bought an used Canon 1Ds from KEH and it was in great condition.
