I have one it is a cheaper version it cost about 100.00 retail. whistler wic1249c. It is more considered an inspection camera.
Very handy, has contrast adjustment, a light and can rotate screen has 2 foot camera cable and is compact. I use for general purpose, checking cyl's, looking for a dropped bolt in obscure places, inside frame rails for internal rot, quarter panel lips for the same... many uses
con screen is a bit small at a little over 2" I would recommend a larger one depending on what it is you want to do.
