I got
this Compustar CS4202S remote start kit with tilt switch and installation for $200 on my winter beater a few weeks ago, and I love it. It is my first time ever having remote start, but it always works. My co-workers are impressed I can start my car from my desk, so I guess the distance is good. Comes with one 2-way remote and one 1-way remote. I use them both daily, keep the 1-way in my bedroom so I can start it in the morning and the 2-way is of course in my key chain. Has an option to turn on the rear defrost if the temp is low enough, which is great for Western NY weather. I've read if your car has push button start, most likely the car will turn off when the door opens. For what it's worth, I had it installed on a 2003 Buick Park Ave.
A lot of times it is on sale for $250 with installation, but I was lucky when I got it for $200. Looks like it is "on sale" for $350 right now, but if you have time to wait it will probably go back down to $250 again.
