I've used Mpix for prints up to 19x24. They are quick to ship and all but one came out very nicely. The one was quickly replaced by them and on their dime. What I'm not crazy about is their size selection. They have many to choose from, but if I want to print something a little off size and I try to get it to fit one of their standard print sizes, their cropping process leaves a lot to be desired IMO. They have red lines that show you were the crop will be, but I've learned it's not the most accurate system. For anything standard, they are fine. For the time you need to crop in their system, cross your fingers. I'm ready to try some place new, but would have no qualms using Mpix for most everything else.
