I agree. You can start out with an 8x10 without breaking the bank. You can hunt around for deals--they are out there--and alternatives like x-ray film and enlarging paper will save you money, just as will adapting a surveyor's tripod to 1/4-20 for the big camera. Decent lenses that cover the format can still be found for under $400---and barrel lenses for much less!
Two thing$ to con$ider:
1) Bellows----these are very costly to replace but if they aren't too-too bad you can patch pinholes.
2)Film Holders---I haven't seen any deals on these in quite awhile. Used $50 a piece is about as low as you'll find, but you can get by quite nicely with just three for starters.
A simple piece of glass will print your contacts, so no need for and enlarger or even a scanner.
