Next up in our impulse purchase accessory week is this 3-source HDMI Switch for under $9. There's no power cord to further burden your entertainment center, and while you can manually switch sources, the switch will automatically recognize which input to use based on power priority. If you're running low on HDMI ports, this is a simple, compact, very cheap solution. [Amazon]
