Terk HDMI-31 Smart HDMI Switch (3 X 1).

This thing works great, and looks pretty good too. The status lights are blue, and a very bright blue, that you can't turn off unless you unplug the thing, so if you need to sleep in absloute darkness, don't put this in your bedroom. It also can be use with HDMI switches.

There are switchers out there that comes with a remote, at a cost of $50 or so. But the fact that this unit is auto-switching eliminates the need for a remote completely, and avoided another remote to clutter up my coffee table. The switcher can also be placed out of sight because of this feature.

Just remember to turn off one unit before turning on another unit for the auto-switching to work properly. Works like a champ with no static or green dots. AC adaptor is tiny, making it quite "power strip friendly".
