I can second the recommendation for Beau Photo. I order alot of my darkroom supplies from them. They seem to have a wider selection than Lens and Shutter. As a BCer who actively avoids Vancouver, I've not been IN any of the stores. Beau has always been very friendly and helpful with mail order.

If you want to be completely overwhelmed by choice - go to Glazers in Seattle. I've been there once. Wow!
