I had good luck buying my own cable and connectors from Markertek (
www.markertek.com). They carry Canare GS6 cable which is good stuff. They also carry Neutrik and Canare connectors. Check them out.
If you are wiring a rack or
pedal board I highly recommend the George L's cables and connectors as well. These are convenient since they require no soldering. However, the George L's feel like mini TV coax. I prefer the more traditional feel of the rubber coated Canare cable for my main guitar cable.
