seriously I just went through this at my new house.... these salesmen all suck royally and will ******** out their faces as to why you need their company... the reality is that there are 3 monitoring stations in Houston that ALL the companies go through... so what you are really paying for is the equipment and monthly fees... for that I've gone with Watchdog Surveillance... $19.95 a month and my total equipment/install charge was $450 for 1 panel, 2 keypads, 1 motion sensor, 4 door sensors and 5 glass breaks.... also, this is for an old house so that was total install... it would have been cheaper if the house was pre-wired...
I used a company that is owned and operated by a fellow Hornfans poster. I used them and cannot say enough about it. To this day when I have a question, they are there for me. PM if this interests you. Though I did have the opportunity to ban them if they messed up, which they did not. I am very happy.
