Ilford have opened a B&W/C-41 and E6 film processing and printing lab in California. From what the site says it includes sheet film in 4x5, 5x7 and 8x10.

Might give an alternative to some who don't have darkroom access. Depending on how well they do it may give some a good comparison of print quality by ordering a print from them and then doing it in your own darkroom and seeing if you measure up?
