Having tried out quite a few of the usual suspects (Van Damme, Klotz, Mogami, Sommer, etc) with a range of simple to esoteric plugs, I've come to the conclusion that pretty much any decently made interconnect is fine by me ... including humble Belkin and Fisual cheapies.
One thing I do avoid at all costs are the insanely thick microphone cable types or heavily sheathed madness that seems to be the fashion with some - totally inflexible in use and a bugger to fit into a plug.
The only reason I don't use 'freebies' any more is that I've had a few where the plugs fell off after fairly moderate use .... 'nuff said.
