New member.. help needed!

Hello everyone,

I just purchased a 2002 e46 330CI, and I am in the market for a car alarm. With so many car alarms out there, I wanted to get everyone's input on what effective car alarm I should get. Money is no object since I'm spending as much money on the car as I am. Any help given is greatly appreciated.

i use an alpine car alarm, no complaints, not too expensive
