from my experience, B&W, E-6 and C-41

1) Reed Photo does a better job of handling your film, and the prints and scan are beautiful.

2) Denver Pro Photo is a good second place.

I haven't tried the slide printer next to Denver Pro Photo.

I do my own black and white now. I'm close enough to Denver Pro Photo that I'll take my C-41 to them. Minilabs have been horrible to me. I don't trust Mike's Camera, or Target or Costco, etc.
