I have a AMP/Honeywell alarm system installed and I could not be happier. I called other companies for over the phone quotes and it was outrageous fees for my home. I dont have a home phone line so I can see the higher expense but the difference was subtansial! I have never had to use my alarm system (thank god) but have had a couple of false alarms that were corrected over my cell phone instantly. I have recommeneded AMP to all of my frieds and family and my parents recently had one installed and so far are very happy!
