I bought this one earlier in the summer:http://www.monoprice.com/products/produ ... 1&format=2
I am quite happy with it. I have it hooked up with the following: Google TV, DVD Player (passing through the Google TV so together they use one input on the switch), Apple TV, Roku, and TiVo. It works virtually flawlessly. I've had to unplug it once in about 3 months of use, due to it not syncing the hdmi signal to the tv. And that was after leaving it tuned to the Apple TV for an extended period, which disables/enables the HDMI output whenever it sleeps/wakes. None of my other devices are set up that way, so I don't know if the issue would be worse if they were, or if it was even really the fault of the switcher.
Other than that, it's quick to turn on/off, has discrete universal codes for each input, can send the audio signal (excluding DD+) from any input over the optical, coax, and analog stereo outputs (all sound outputs active all the time, including hdmi), and has built-in functions to mute and change between surround and stereo output. The optical audio output was important to me to hook up to my older low-end receiver(no hdmi); I'm not prepared to upgrade that yet
, and this gives me the best possible sound I can get with each of the devices I own right now.
It comes with a remote, but I use a Harmony, and learning the codes for it was a simple one-time process.
It might be more than you need, or at least more than you need right now. But I can definitely recommend it and Monoprice (this is only one of a dozen or so things I've bought with them and they've always been great to deal with). Just be sure you do your research on everything you'll be hooking up through it. If all you need is more inputs on the tv (no receiver involved) and you don't plan on changing that for the foreseeable future, there are cheaper units like the ones Gilgamesh already linked; I'd be pretty confident you won't have any serious issues with any of them, if they meet your needs.
