What controller should I get?

[The Phoenix]

Hi there,

I bought a "Rock Candy" PS3 controller for my android tablet, works like a charm, PPSSPP.
All controls are re-definable, even the right hand analogue stick I was even able to map to the right face buttons (Triangle, Circle, Cross, Square), so games like Star Wars Battlefront 2 etc worked brilliant.
The controller is wireless and uses a full size USB connector, I must say I haven't tested this on my PC yet though, but I shouldn't think that would be a problem.
