Wow, for $80 I would have expected something that would measure dB loss and 
maybe even a time domain reflectometer (well, maybe not that).

I have seen those continuity type testers on ebay for under $10 (the test sets 
with two devices, both with RJ-45 jacks, you plug the ends of the cable into  
those (one at each end of the cable), and then the "master device" tells you 
whether the pairs are connected properly and there is continuity).
