I've been wanting to get a cheap car alarm for my truck since I put the new stereo system in. I know that most of you recommend that I get a top of the line alarm and do it right the first time, but either I'll get a cheap alarm or no alarm at all. I notice that most alarms come with features like remote start, keyless entry, and keyless truck access. I don't need any of those features. Basically all I want is something that'll sound and flash lights when my truck is bumped or the glass is broken.

I found these alarms by accident, but they look like they might be pretty good to me: Commando Car Alarms . Maybe you guys could give me some suggestions on how I could put an alarm together using what they sell. Thanks a lot!
