My online shopping has primarily been done at (Jeff is awesome), (Jim Andraki is also great), and I built my 645 kit from and for cheap, and everything was in perfect condition. I've purchased 4 4x5 lenses from badgergraphic, with great service from Jeff each time.

I've also dealt with B&H a couple of times (ok experience, really expensive shipping), and Freestyle (I bought so much stuff, they threw in some freebies).

I've not had a bad experience with any of them. All recommended.

Oh, I have bought stuff from Calumet, but only from their store in S.F....never over the net.
