Do you think I got screwed, or is it just part of the hobby?

Thanks for the replies guys, It makes me feel better knowing that I am not the only one who thinks they are at least partly responsible for this fiasco. The unfortunate thing is how do you know who to trust in the future. I mean these guys are VERY highly respected and do millions of dollars a year in business, but they can't even put in a wrist pin, rod bearing etc, or proper finish on the cylinders correctly. Hard to find someone who is good at what they do.
