I've recently found what appears to be a very good source for ordering cables.
I recently ordered 2 - 50ft RCA cables and a 75 ft monitor cable for a projector installation we've done at our church. I got the 3 cables with shipping for only $57.59
I've installed the cables, and the monitor cable looks great. the RCA cable is for use with a VCR (if needed). Anyway, the quality appears very good. I wanted to pass it along. I got all the cables cheaper than I expected to pay for just 1 cable.
Oh, and BTW, they have other stuff besides cables.
