I'm assuming you are trying to stay around $300.00 but if you could stretch it another $150.00 This would be a much better choice IMO. Not trying to blow your mind with another choice but it has the dsm radio and i'm pretty sure the engine is legal plus it is a more modern platform. I do agree the jammin is better than the hyper 7 though.
