I bought an 8x10 Agfa/Ansco from Midwest Photo Exchange for $495. The bellows had been replaced, but they work just fine. I got it so I could get into contact printing. As for lenses, I bought a 300 mm f8.5 Fujinon from MPE new, and recently picked up a 159 mm f9.5 Wollensak on ebay.
I agree with a lot of what has been said here too.
