re: Alarm monitoring: How much do you pay?

$47/month for wireless (no phone line) system. "Free" install. I was looking to have one installed and had shopped around for prices. ADT knocked on my door and told me they could do it that afternoon. They were significantly higher monthly than other places, but the install price was a lot lower than what I had been quoted elsewhere. It was pretty much a wash over the 3 year contract, but they came to my house and did it in a day, so I bit on the offer.
