I always buy mine from the bay, and it's ERA.
I've used lots of it, and like it a lot considering the agreeable price.
The guy I buy mine from is Isaac Chen. He's honest, fast and most of the time the film I get from him is just a little out of date, but has always been fine. Been buying from him for the past 4 years or so.
It's 100 speed so I use it for a lot of pinhole stuff.
Only thing is he doesn't sell a lot of film, so you just have to be lucky and catch him when he does.
