Inspection camera recommendations

[jaggedben]

I could use a better inspection camera (endoscope, boroscope) than the one I have... I got a $100 thing on eBay that works as advertised but isn't bright enough or senstive enough to take pictures of large areas inside of crawlspaces, which is what I need. I need something that can light up areas and objects at least 4-6 feet away and take a decent enough picture to tell if one is looking at vacant space or seeing something. I would be mostly evaluating the structure of crawlspaces that don't have any access. Can't make large holes in roofs, the one I have only requires a 3/8ths hole and that's good.

Any suggestions? Experiences?
