Subwoofer cable recommendations please?

Would like recommendations on good quality sub cable(RCA) 25-30 ft. Budget $100 used. Thank you.

Same situation Rick!!! Our paths cross too many times!!
I will keep looking for suggestions as well.

I've had good experience with Better Cables on long runs
If you can find them used, Analysis Plus has what they call their Sub Oval Interconnect. I am using it in both my HT and "music only" systems, and like it much better than the high priced garden hose I replaced. New price is a bit over your stated budget.
I have been using a 10 meter Audioquest Ruby cable. I think you can get a pair of them for under $100.
Nordost bassline subwoofer i/c! inexpensive flat and it WORKS!
