HDMI switcher

I have a samsung DLP set w/ only one HDMI input. I was looking to get a HDMI switcher, but i'm not sure which one to buy. Is there a quality difference between different unit's? What kind of spec's should I be looking for? Any reccomendations?

While I can't speak to the specs, I've been really happy with the products I've gotten from MonoPrice.com, and they seem to have great prices on those switches.

Does anyone have the HDMI switcher from monoprice? How are they? I see that they have a couple of different kinds, one with a equalizer, and a manual switcher. What does the equalizer do?
