A&I in L.A. is a fine lab. I use their E-6/K-14 mailers frequently. They also do nice C-41 machine prints--pro quality at half the cost of New York pro labs, but if you use the mailers you obviously have to wait for them. www.aandi.com.
My favorite local New York lab for all around work that I send out is Modernage. I don't know that they have a decent webpage yet, but you can get their phone number from www.modernage.com and request a price schedule which lists all their services. They're very comprehensive, friendly, and do very consistent work.
When I was a grad student, I used to earn some extra cash by shooting actors' headshots, and the best lab for headshot repros in New York is Kenneth Taranto.
