I wouldn't recommend installing them yourself. A lot of alarms must be professinally installed or they will void the warranty. You might want to check out the documentation on the alarm you get.

From personal experience, I have a $200 Avital alarm from Bestbuy and It works great. Hardly any false alarms. It doesn't have remote start, but I have a 5-speed and its a hassle to go through the routine to turn off the car.
