So, what did they do to it? And I'm not asking in any way to be argumentative, but more info helps us all. If my one and only experience with them was my 60-250, I might not be feeling in the OK zone. And the 60-250 is an enigma. What happened that it wouldn't focus to infinity after they cleaned it? I'm assuming something got put back in flipped/out of alignment etc. So perhaps I should be more wary, but then again, I've got to think for something like a factory upgrade, they will have specific training and no questions on what to be done or how. I also look at all the "big boys" who use them as their authorized repair center and have to think they must have some level of success.
