I'm looking to buy an inexpensive borescope and found many on Amazon starting in the $20 range and going up from there. I like the idea of the USB scopes that plug into a laptop and I even found one that had a dual USB/Micro USB plug. I would like to be able to see into my cylinder heads and also help locate oil leaks among other things. I can see where these could have a lot of uses.

Any recommendations?

 

I have been looking at the USB one on Amazon as well. A co worker just purchased the Milwaukee one but he needs to see in water with it. $20-$40 its a risk but worth a try. I use an old fiber optic scope that barely fits through the spark plug hole.

Think of the money you would save with a DIY colonoscopy.
