if i were going to try and get a cheap project quad, id much rather have a 250x or 300ex than a blaster (is it a bigbore, since u said it was a 250?). blasters motor has potential to be fast, but those hondas last forever. plus the overall chassis/layout fits someone thats normal adult size, unlike blasters, that i felt cramped on when i was like 15 (and im not even big). neither is a bad choice if u find the right deal, but overall the honda handles better is around as fast and more reliable. just dont explode it cause then it would cost more to fix (since its 4stroke)
