I generally roll my own cables. I get bulk cable from Mark and Liz Hellinger at
http://www.audiopile.net/. It's EWI (Korean) and it's some of the best I have used-yup, including Belden. Their quad mic cables can't be beat. I use this instrument cable:

The 20 footer is $8.50 and it is excellent. Period. I can't save any money building my own...and this one is just as good. I use right angle plugs coming from my bass, then pass the cable between the bass and my strap.
I cannot say enough good things about Mark and Liz-just a little operation, but their candor is amazing. They also market a fine active DI for $50.
