Praus looks good but is pretty pricey. From that LF thread, Citizens Photo in Portland is way cheaper on 120 than anyone else (3.75/roll vs 8.50 at Praus) and slightly more on 4x5 (which I dont have much of anyway). But I do want to be assured its good, too. My previous labs were all in the PNW and did great work, if that means anything.
I found out my local photo shop still does C-41 at $5/120 roll, but I have no experience with their developing and they don't do 4x5.
