Control your home theater with Logitech Harmony universal remote, $39.99 (after rebate)
TigerDirect has the well-reviewed Logitech Harmony 550 remote on sale for $39.99, though you'll have to wait on a rebate to get that price.
Update: I'm not entirely sure what happened with this, but the price is now $69.99 after rebate. I tried contacting TigerDirect to see why the original price disappeared so quickly, but did not get a reply. All prices that I post are accurate at the time I post them, but unfortunately sales sometimes end without warning, inventories sell out, and so on. My apologies for the confusion over this deal!
Tired of juggling remotes? Replace them all with the Logitech Harmony 550, which sold for $150 when it debuted a couple years ago, lists for $129.99 now, and is available from TigerDirect for just $39.99 (after a $30 mail-in rebate).
In case you're not familiar with them, the Harmony remotes are renowned for offering (relatively) easy programming via desktop software, which is available for both Windows and Mac systems. Just choose your home-theater hardware from an extensive database, then set up your desired activities ("Watch a movie," "Listen to music," and so on). The remote's built-in help screens walk you through any problems that may crop up (like the TV turns on but the receiver doesn't).
I've used several Harmony remotes over the years, including this one, and they've largely been outstanding. My only gripe with this model is that it doesn't use rechargeable batteries. But for 40 bucks (plus $8-9 for shipping) it's absolutely impossible to beat. Don't take my word: Check out, and be sure to browse the user reviews as well for more real-world testimony.
