Unless you really need the turnaround time, I would suggest just using Calypso in Santa Cruz, CA.
I find it funny, and I don't mean you personally, but it seems like so many people here are so picky when it comes to how they develop their B&W, but are perfectly willing to send their transparencies off to any old lab. The E6 process is much more succeptible to processing variations, IMO, than B&W (I'm sure Ron can set me straight if I'm wrong). What I like about Calypso, besided the customer service, is that their process is continually monitored for quality - that means my slides will be properly processed and clean.
