Cool new tool

I was looking at Wally world and found this cool Borescope w video display by Whistler. It was only $79 and best of all it has smaller lens-tube that will fit thru spark plug hole. I don't know about quality but could solve problem for somebody. I picked up similar scope at HF but it has bigger lens that won't go into sparkplug hole. I have used my scope on car repairs and home repair several times in last year.
