I am almost coming to that conclusion myself. I have spent a lot of money on pre-buys by mechanics that had outstanding reputations. In both of those cases, obvious things were missed an wheelborrow loads of cash were infused into the subject aircraft.
The only one that I didn't shove money at was my original 150/150 that I bought without a prebuy or even having flown or hearing it run. How's that for bright as a 2 watt light bulb. <img src="/ubbthreads/images/graemlins/blush.gif" alt="" /> <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
