I can't say I have an obsession but I have more parts prepped and stripped that I could possibly consume myself. I am not doing as much technical research and study as I should. People talk about "doing something you love", well I like working with my hands and I sure ain't making money with PC'ing. It affords me the ability to maintain or buy more Vmax stuff though.
I really respect and enjoy our community but I'd be lying if I said its all roses and sunshine. While my cores are usually of the highest caliber, I do get sub par parts in exchange. I've lost out a few times with "unusable" parts of which the pile is getting larger but I learned a few lessons and try to out a caveat out that if something is damage or worn beyond reason, I must be able to back out of a price or deal. I disdain having to do that and will do whatever extra needed to make it work out. Sure there are days where I just don't want to sit with my face in a media blaster but I try to treat all as I would hope to be treated.
In the end, there are probably enough guys just on this Forum spread out the USA to preclude anyone to having to start their own PC ing venture but local shops can do good work. Not all are reasonably priced. If you think you might enjoy seeing results of your own handiwork, go for it! There is plenty of us willing to help.
