I got my own personal Endoscope....
I know what you're thinking...and no....I plan to use it for looking inside of the ceilings and walls, maybe an engine block and such too. It doesn't have a real great resolution, but as good as the ones that you get from HF with the screen on them. The focal point seems to be about 3" in front of the camera, about 12" away you can fit in an object about 4" tall with acceptable detail, and 2' - 2.5' is about the distance you really start to lose rough details.
This was my finger about 3" from the front of camera. It has 4 LED lights that can be dimmed if needed.
The cord is 5 meters (about 16') and the camera end is only about 7/16" in diameter 3" long. Just plugs into the usb of my laptop and can use the webcam software to view it on the 15" display. Will probably have to tape it to the wire fish tape/rods to be able to control it much though. Was only about $21, so if it helps me even once it's worth that price.
Got it from amazon... http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
