They pop back up periodically. This one is very close in design to the Xbox 360 Harmony remote they had. I have both for my two setups. The 360 one has a little nicer feel to it on the buttons, and it has the X, Y, A and B buttons. I'm not a huge fan of the color and green backlight though. This one looks nicer with a black/silver color scheme and a blue backlight, but it's lacking the 4 extra buttons. Either way $50 is an awesome deal. Sears.com has been running sales on it for $59 since black Friday. Keep checking their website, and it might pop back up. I rarely see deals on the 360 one though.
These are great for anytime you change anything (add/remove components, change cable hookups, etc.). Anything that can be controlled by IR can be added to these. Setup is done through a website and is pretty simple once you get the hang of it. Once it's configured with the defaults, you can customize to your heart's delight. I configured mine to use one of the buttons to cycle through surround modes on my receiver.
