It is much cheaper to get your self a traditional 35mm film and a digital camera, than a film/digital hybrid.
The top of the line Canon EOS D30 (3.12 milions pixels) would cost you $2500.00, and the top of the line Canon EOS 1v HS body is $2000.00. (over 40 EOS AF lenses)
If you must get a all in one traditional 35mm film/digital camera, then the Nikon F4 or F5 body with Kodak DCS 620x digital back (1.99 milions pixels) is the only option, and cost at least $6500.00 (sugestive retail $10500.00). (over 30 AF lenses & over 30 manual lenses).
Personaly I would get the traditional 35mm & separate digital camera body for less & higher quality, be it the Canon or Nikon flavor.
