I've used these folks for over 10 years. They're a small outfit but their quality has always been stunning. I have more than a few 20X30's on public display that these folks have printed. Can't reccommend them highly enough.
I print from E-6 (in fact any film) via an Epson 3200 scanner and an Epson 2200 printer. Cheapest way, relatively that is, so far.
Instead of printing on an inkjet, go to www.adoramapix.com . Photo quality prints, shipped to your door for not very much $$.
I've used them on well over 4,000 prints, ranging from 4x6 to 16x20. They always do a fantastic job.
My lab charges $8.00 for an 8x10 "machine print" from from either color slide or negative. The "machine" is a Fuji Frontier (sp?) that can make an 8X10 (maybe larger?) from 35mm, and 120 film. This machine is fairly comon. I think this is what you'll find at your local Walmart too....
