Good bluetooth controller for unrooted transformer?

[mgamer261]

Have an Asus Transformer loaded with emulators, but the touch controls are really starting to bother me. Any recommendations for a decent PC bluetooth controller with analog sticks that will work with an unrooted transformer? I see gamestop offers a controller with their tablets, but I have been unable to find it by itself.

I've been looking into this too, I'm going to buy a Prime when they decide to stop dangling infront of our faces like a carrot. Anyway, look at "onlive". It looks pretty promising. Supposed to bring console games w good quality to tabs. They also sell a nice looking controller that is supposed to work w the og tf.
