A company called Accell ( offers a variety of video switching and splitting options and cables. Their products include the tiny UltraAV, one-in, two-out HDMI splitter for $129, and the UltraAV HDMI two-in, one-out HDMI switcher that's smaller than its included remote control. Both are powered by external, wall-wart supplies. We plan on checking both of them out soon.
