Last week, I was at an adult shop, and I ran across an adjustable cock ring called a Lasso. It's made of surgical tubing with a bead with a pushbutton that you can slide down the tubing and tighten. I have found this to work very good for constrictors. Not as cheap as cable clamps, cost about $12, but for me it is very comfortable.
Anyway, if anyone wants to check one of these out, just do a search on yahoo or google for 'lasso cock ring"
