as the title says, has any one used one of these?

I've got a lead on one for about $35, 10 inputs, 1 output. I am wondering if I should go for it or not.

for any one that's wondering its a multi format A/V switcher, they have much larger versions but I cant imagine having more than 10 systems hooked up to my PVM at one time.
it supports RGBHV, RGsB (sync on green), RGBS, Composite, S-Video (via adapter cable) as well as switching stereo sound on each input
