I'd stick to the MS one, but I've never been a fan of Madcatz / Hip Gear / Pelican / etc for anything, really. If there was a Logitech one, I'd be more apt to recommend that one, but I don't think that there is.
Oh, and Big C, can you rework that sig so it doesn't bounce up and down (the color part moves up and down within the black background). It's giving me a headache.
