Since I am going to be buying my system soon, my parents said that they would purchase me an alarm for christmas. I need your ideas on some good dependable alarms. My parents are probably going to want to spend around $100-$150 on the alarm. I don't need anything crazy like a remote start, I just want a dependable, simple alarm with a good range. I was thinking about getting a Compustar 900. Also what am I looking at to have this installed?
