Damn, glad theres a happy ending. Get a Compustar Alarm (1.5 mile range, pager system). It would have notified you in class (vibrate or beep mode). Also get a AutoLock for the brake pedal, and a AutoTaser (ear piercing alarm when theres movement in the vehicle. You could of had it go infront of your radio, so if the dip **** thieves touched it, 50,000 volts would be going through their bodies.
I have the alarm and autolock. AutoTaser is next on my list.
