Hi Gang,
I bought a ProVision PV2 (I thought from ACS) for about $150. The tube is somewhat flexible and allowed me to inspect my valves and cylinder, etc. last oil change. But, the view was not nearly as good as the posted photos and I have nothing saved for posterity & comparison.
I love being able to take a look inside. I appreciate these posts. I'm getting ready to spring for some type of dental camera, even if its wrong.
Cheers & thanks,
