also keep in mind that most blasters came with cable operated front drum brakes and a cable operated rear disk brake. (sucks, don't work, PITA)
I bought one for $600 two days later i started a rebuild with new wiseco crank, pro-x piston and a number of other parts
most folks will get rid of thier blaster when it is on its last leg, and as for buying a rebuilt one ...I would never do that, it would be better to buy a blown up one on the cheap and go through the engine yourself.
I think in 03 they came with hydro brakes.
I traded my blaster for a wallard out warrior about 4 weeks ago.
unless you have riden one and like the darting around handling that the short wheelbase produces, or have a ton of money to extend the swinger, buy aftermarket suspension, and convert it to hydro brakes,..I wouldn't get a blaster
