Car Alarms: Isuzu car alarm beeper, joe cassidy, replacement remotes

Question
Gentlemen; I have a 2001 Isuzu Trooper which came with factory installed alarm, included two beepers. I recently lost one of them and need to replace it. At our local shop they were asking $195.00 !!!!! for just one beeper. My beeper has two black buttons plus a red one. I do can open the doors and start the engine with the car key without the need of the beeper. Is there any place in the USA where I could get it cheaper? In the back of the beeper it has some letters and numbers: FCC ID:HYQ1512R < Canada 1551-102-581  ;RSS-210  DENSO. Can you help me?    
Regards,   Raúl ( Puerto Rico )
