Dang why no love for the blaster? I had one when i was younger prior to getting the 660, and i loved that little thing. I beat the piss out of and it would always start second kick, and was easy as hell to maintain. It's a great machine for what it is, i never had an issue with the brakes, really don't get that one. It isn't a 2010 model and shouldn't be compared to one, and doesn't stop on a dime, but that issue is being really inflated.
As far as the one you are looking at, $1200 is steep for one in that condition. I sold my 99 for $1200 and it was in great shape. Even if you found one in great shape, they really don't go for much, so unless you could find one for a few hundred to fix up, there is no money to be made with flipping one.
