they sell that one at Best Buy and gamestop for $20-$25
I'll sell you one cheap if you want it, I'm getting rid of it because one of the inputs stopped working after a few months and all the ports on the back are loose (and it just friggin sits there).
If you're looking for a high quality switch, and cost is no object, I'd highly recommend the Audio Authority 1154a. It goes for about $200, and auto-magically switches inputs for you. It's got component video, analog and digital audio in both coaxial and optical forms. So you can tuck the whole switch behind your display and forget it even exists
If you're looking for a mid-grade switch, and want remote control, I'd recommend the Psyclone PSC01, available at best buy for about $80. It's got 4 inputs and does composite video (or coax digital audio), s-video, component video, analog audio, and optical audio. it matches the home theater device layout and has an LCD that displays the currently selected device. I recently went through SEVERAL switches to find a nice new one and decided on this one, it has fantastic signal quality (much better then the pelican switch above)
If you're looking for a low-grade / cheap switch, there are a number of options. NONE of these switches will do optical audio as that would require power, if you get a powered switch make sure it's a high quality one or the power will introduce lots of interference.
I would also recommend AGAINST using composite/audio switch for component video as suggested above. Certain video types require different standards. So it'd be hit or miss if the switch you picked up didn't meet the required standards for your signal. Considering MOST cheap "HD capable" component switches don't even meet the minimum required specs I'd say only get a cheap composite switch if you really just don't care about your video quality.
