I have a cheap solution. Simply don't own anything of value and make sure you have some type of insurance! If they get your $150 TV, you get a new one. You were going to get a new one anyway, weren't you?
I figure, if they want to get in bad enough, they're going to get in. We do dead bolts, but with key bumping, there's a good chance those are weak anyway.
I tried the x10 device route, but something's weird with our wiring "phases" or something. They don't work everywhere. They do save us time in going out to turn the Xmas lights on and off, though!
Some people are like slinkys. They're useless, but it's fun to push them down the stairs.
