Anybody have experience with them? Know of a forum for such type of tools? If so, PM me or post in the Lounge. I have questions, but the discussion doesn't really belong on an auto forum.
Idk know much bout this, but I do know local hardware stores rent them out. Our job bought a cheap one from amazon, was good enough but for 375$ did not have enough length of boroscope, so we rented this unit at home depot. price of rental unknown.
