Borescope recommendations (features) [solved]
I'd love to get a borescope, but I've never used one. Should I try to find a place to rent one first (does such a place even exist?) or should I bite the bullet and buy one? What features should I be looking for?
Specifically, I want one to be able to examine inside walls in preparation for running wire, (i.e., Cat 6, coax, ROMEX).
This one has really good reviews on Amazon, for what it's worth. It comes with 3 attachments: a hook, a mirror, and a magnet, all of which sound like nice things to have. There are also extension cables available for going longer distances inside the wall (the included cable is 3 feet). Here's a pic: 
The price seems really reasonable at $160 (as of Nov. 2010). My guess is that if you went to rent one, you'd be limited to more commercial-grade models and that if you wanted to keep it for a few days you'd be looking at something close to that just in rental charges.
Harbor Freight has one for US$159.99 (right now it's on sale for $119.99). It's in-store only, but here is the page on their site. I don't have any experience with it so I can't make a recommendation.

$60 - plug it into a laptop - can take pictures
I never run wires without using this first
If you don't need a semi-rigid cable, Teslong makes an inexpensive USB borescope with a 50' cable ($28). I've used this with my laptop to examine my HVAC system, and it is apparently compatible with most smartphones (although I haven't had any luck finding a USB adapter that fits my Google Pixel).
