Im really surprised that your micro-E was a lemon like that. I have had my micro mag (not E, but getting the hyperframe soon) for some time now and have had absolutely no problems with it *knock on wood*.
Im even more surprised that the customer service gave you a long run around like that. when my friend stripped the holes on his ball detent off his micro, he sent it in to PTP and they patched her up and had it back fast in less than a week.
This truely is a nightmare and a shock to the AO community. Im glad you got a nice new toy, and that its shooting like a dream.
