You're gonna recommend that alarm soley because it has a good proxy sensor? Wow! If you were to compare Alpine and Clifford head to head, it would be painfully obvious that Clifford is the superior of the two. Does alpine have a wireless immobilizer? what about a tilt/motion sensor? a anti-carjack system? or what about dual zone omni sensor? are all of the sensors remote programmable? and now here's the most important of all questions, is the alpine "always on"?
