You can never be too rich, too thin, or have too many HDMI ports. If you just added a component to your home theater (a Blu-ray player, perhaps? Wink, wink) but don't have a port free on your TV, check out this no-brand 2-port HDMI switch. It's available from SuperMediaStore.com for just $22.99, ground shipping included!
The switch supports HDCP and resolutions of up to 1080p. It's a self-powered manual switch, meaning you'll have to haul your bum off the couch whenever you want to change inputs. You'll also have to supply a pair of extra HDMI cables; the same store sells them for $9.99 apiece (when you buy at least two).
