Yeh, been looking at monoprice.com. I have already bought 2 audio cables
from them and so far pretty happy with them. They do have a CL2 rated
silver coated(?) and gold ends 30ft VGA for a fairly reasonable price.
They also had HDMI cables for as low as 10.98 25ft. It was standard
speed so I'm assuming that means HDMI 1.x whereas High-speed must be
HDMI 2.x. They do have a DVI-HDMI that is 30ft, not sure on the price as
I was mostly looking at HDMI or VGA. I haven't seen any HDMI with swivel
ends yet, do you remember any sites that you saw them at? I'm intrigued
with that concept, might come in handy for me.
