I got a PS3 Slim for Christmas and the one thing that bothers me, is that it is a bit shaky in the vertical position. So a finally decided to get a stand and went with PS3 Move Power Stand. I have to say it is awesome. It is a bit expensive, but you get so much for the price.
You have spots for 2 DS3's, 2 Move controllers, and 2 Navigation Controllers. It also gives you 4 extra USB ports. It has a built in USB cable that plugs into you PS3 and it syncs all of the controllers at once to the system. The area that the PS3 sits in is soft rubber so it won't scratch it, but fits very snug. It isn't going anywhere. Just wanted to give my thoughts on it and recommend it to anyone looking for a stand with extras.
