Oh, I misread that, I thought you wanted a URL for the under $10 device.  Try 
googling for time domain reflectometer, I don't think you'll find one for even 
near $80 (but I'd love to be wrong) -- maybe a cable loss tester at that 

Some URLs for under $10 testers (prices have changed ;-)  (Prices are a little 
over $3)

From a review of that one:

Excellent cable tester!

Plug in both ends and watch for the lights. It's as easy as that. Great for 
testing Ethernet cables to rule them out as the issue.
Requires 1x 9v battery.
