ive read on another forum that the 15" is $1500 and the 12" is $1200. im guessing he got it straight fromt he site. if not from a store that may carry them.i never hear anything about the new strokers.... how much are they? how loud to they get? at the spring break nationals a guy talked to me about them and told me it had some new magnet technology that made it considerably louder than the old stroker.
