Accell's HDMI switch allows you to plug in two HDMI devices at once—no more traipsing to the back of the set. Plug in your new Blu-Ray player, HDTV DVR or Xbox 360 (HDMI coming soon) and switch between the two with their bundled IR Remote Control. The switch doesn't require an external power source, and at $99, is much cheaper than the $250-$300 for similar devices.
Available in June.
Update: Reader George found a 5 port HDMI switch for $130.
