i asked the same qeustion a few months ago and got a lot of the same responses. i looked into the reviews posted for the various companies and went with frontpoint. very easy to install, price of equipment is low, monthly is about the same as the rest. it can even be connected to wired home smoke alarms and other existing in place wired systems with a bridge (about $40).
let me know if you have any questions, install shoudl take you about 45 minutes (seriously)
