Yeah I went ahead and did a test of the online photo printing companies. Ofoto vs. Shutterfly. Ofoto clearly won. It seemed they sharpened the photos even a little bit more than I had, but not so much that it was overwhelming. It just looked crisper than with Shutterfly. The one exception was with a shot of Rocky Mountain National Park, where a mountain skyline came back looking like the top had a halo because Ofoto over sharpened it. Overall though, i would say Ofoto wins.
From what I hear, however, the best printing company on the net is www.mpix.com. They print in sizes native to a DSLR, which is very nice, instead of making you resize to a 4:3 ratio at larger sizes. Their per print price is also a bit cheaper than ofoto in most cases. The only difference is that their photos cost $4.99 to ship, where as Ofoto/Shutterfly's shipping is around $1.99.
