I should add.... I picked out the Lynx about 5 years ago when it was the hot thing. And I'd used ADEMCO products for years.
Its an old platform and doesn't program very elegantly. But it gets the job done reliably.
If I was starting over I'd probably look at one of the new systems. My neighbor went with the GE Simon system, I like the step up from that, the Simon XT. Here's a link to a basic kit with some contacts and motions.

That gets you started and then you map out the contacts you need, smoke/heat, other misc things. I prefer direct contacts over glass breaks. Glass breaks are notoriously troublesome if you try to use them to cover a whole room or area. Installed directly on or next to a large window like a sliding glass door or picture window then they are great. I don't alarm large picture windows in the front of the house. I just let a couple of well placed motions be the catchall. Doesn't go off when you're home though. But I'm just not thinking the home invasion robbery is coming through the huge picture window on the front of my corner house for all to see.
There are other brands out I don't know much about. But the warning is that go with a brand and series that is going to be around for a while. Wireless contacts/motions/etc are the things the ultimately you're going to spend the bulk of money on. The Ademco 5800's have been around for more than 10 years and have a huge selection for different needs. Not true with all brands. And rarely do they interchange as they are on different freq's. GE Home Security has made a big investment, so I consider their line pretty safe to be around for a while.
