There are just so many choices out there. Most people think the safe choice is buy the paper "made" by your printer maker, but some go a different route.
I've used
Red River Paper for the past few years and have fell in love with it. The paper works as well if not better than the Epson/Canon paper I had been using and is much cheaper, with a better selection. I like the 68lb photo gloss.
What do you guys use?
