I sleep so darn hard I could be robbed and the robber could be eating Dorito's next to me in bed watching sportscenter while drinking my beer. They only reason I'd wake up is because I had to take a leak. Weird how pee dreams wake you up just in time.
So that's why I use Claymores, but there again it'll be the police shaking me awake to ask WTF happened.
All joking aside for average joe get a good old fashioned scattergun as my grand pappy would say. I prefer pistol. I train with it, know where it will hit just by pointing it and I don't want to find flesh a month later in my hallway light or somewhere else I forgot to look. Yuck!
Putting up motion lights and an alarm company's sign in your yard will work 89% of the time. Leave no entry point in the dark.
