Crimestopper RS-999FM I bought it on ebay for $90. I used to install alarms and stereos 6 years ago and really liked the DEI product line (clifford, viper, rattler, and all the other snake brands) but there stuff is way to fancy for what I need, all the 2 ways I saw were 300+ , and they only advertise a range of 1000 ft, which is fine for most people but I need something with longer range. So I went with a second rate brand, I'm happy with it so far but I've only had it a couple weeks so far.
Depending what kinda car you have you might be at the mercy of what retailers carry and intall. With all the new car databus, transponder and passlock technology out there it's getting more and more difficult for the Amateur to do it themselves.
