http://cgi.ebay.com/Contax-645-W-Kodak-Pro...1QQcmdZViewItemHere is an ebay item for a complete Contax 645 with 120mm macro lens and the Kodak DCS Proback currently at $2,001
Not sure what price this will end up but seems low at this point
Might be a good way to get into mf
I think the back had 40,000 shots
FWIW
