if your only going to have it for a year i would find one that doesnt need a rebuild anytime soon, you should be able to find one cheaper than that. but if you did buy it and run into problems the guys on here can help you through them, banshees are really easy to work on,i rebuilt the entire engine myself when i was 16 years old. i bought mine for $500 blown up needed cylinders and i ran great.
if you go for a new one good luck finding one because they are no longer made, but if you do find one the resale in a year in a half is goin to suck you wont get much for it,
and whats all done to the blaster? i dont know anybody that would buy one for that kinda money, if its stock anyways
