There's also Colourworks, in Wilmington DE at $6.25/roll. I haven't used them yet, so I can't say anything about quality.
I have used Colourworks for 70mm C-41 developing, and they were excellent. I have had E-6 done at Philadelphia Photographics, and they have top-quality processing as well. $7.00 a roll is not bad either.
