I used to use Central, and I was happy with them, but then began mailing it out when it was cheaper to do so.
I just stopped by Central, and 120 C-41 and E-6 are each $6.99/120 roll, processing only (versus Gamma at $7.50). The turnaround is 2 weeks.
I have 20 rolls of 120 E-6 and C-41 from my vacation which I just returned from; I'll bring them to Central tomorrow.
