I have a compustar 2wss and it works amazingly. The remotes work further than any other brand, and it has a lot of good features as mentioned above.
With a manual trans, you pull up the ebrake, pull out the keys (car stays running), get out of the car, and shut the door. The alarm then shuts off the car, locks the doors, and arms the system. This way, you're always guaranteed to left it out of gear. If you didn't let the alarm shut off the car, the remote start won't work.
