I do not regret my wire stripper, one of the most valuable tools I have. I got about $34 worth of #2 copper spending less than 40 minutes stripping car battery cables and cutting off the ends. That said I don't bother to strip every wire I collect. I still take loads of low grade and #2 insulated wire to cash in large and small.
I would never bother to try and strip cat 5/6. It's a PITA enough just making the cables. I got $.69/lb my last load of them not sure if that's good as a nationwide price but it's OK here.
