i bought a crimeguard from crutchfield.com. it was the best one they had and was around $250. it was really easy to install because it came with harnesses specific to our cars. a few splicings here or there. the hardest part was making everything neat. while i heard some people say that crimeguard isnt the best you can get, i think it has worked pretty good over the last year and a half i had it. it comes with motion detector which is really sensitive, a microphone that detects glass breakage, shock sensor, keyless entry, just about everything you would want except trunk pop.
