Found a Macbook Pro on craigslist for $700. Inquired about it, said its got a problem with crashing once every 5 startups or so, so he would let it go for $450... insisted that his local apple store said it would cost about $200 or so to fix the problems (but never told me exactly what was wrong, just that it was a 'software' issue... that reinstallation of OS didnt fix). Told him I'd pay him the $450 if he met me in the apple store and they confirmed $200ish to fix the problem. Well, he said he isn't available to meet in an apple store due to a busy schedule on the day i asked him to meet, so i said i'd pay him $250 cash and walk with it. Would this be smart, or stupid on my part? I realize that a new logic board would run $400ish, which if i had to replace would still be a decent investment. THOUGHTS???? SUGGESTIONS???? specs on it are 2.2ghz, 120gb hd, 2gb ram. again, he says it crashes once every 5 times or so he boots it up. $250 cash.
