Query: The best Canon value for that perfect shot... but step up quality control Canon!

This really is the best Canon value for that perfect shot! My only down side is that there are some soft qualities about it and I still can't find a flawless lens. After returning two others... I still see imperfections in the glass. I think Canon needs to step up their quality control on this one. This doesn't seem to affect my photos, but it's not true prime glass quality. Otherwise, when it spot on... this one makes you smile. Totally worth the cost... My only down side now is that I want the 50mm 1.4! :)
