Stereo & Electronics - Best Security System for Cars?

So what's everyone's opinion on car security systems?

LoJack seems alright, but if your car is worthy of being stripped, it could be parted down before it's found.

In my searching I've found (in theory) the PowerLock to be the best option. Well, redundancy with a mix of systems seems best overall, but still.

I was thinking about getting one.

Anyone using this?

I want the clifford with the key fob that shows where your car is and if an alarm goes off it has a pager built in that tells what zones on the car was hit

Damn, that Matrix GPS tracking system owns.
