sorry i dont know anything about the buster, but you could try http://www.racekites.com as they have loads of reviews, its free to join and it will give you more advice, a friend when i brought the beamer though i had got it to try buggying but not being a buggy user i would hate to say it was suitable if it was not or vice versa, as i say try recekites for more advice. hope this helps.
cheers
