I was looking for motion sensors for the smallish areas around my security system and found these on eBay. $4.68 or less each. The seller is selling basically the same one that many others are selling, but with no lead or instructions. I bought the 3 pin leads on eBay for pretty cheap too.
I've been testing these on my desk, shooting it down a long hallway that my desk faces. I think the line of it is somewhat narrow, but I was getting motion even 30' away. They have a delay time selector on it, I haven't messed much with it yet though.
