In the most recent EGM, there was an ad for a device for PS2 that allowed you to make any controller a wireless controller. You connect the receiver to the console and the transmitter to the controller. It comes with a battery adapter or something like that for the transmitter. Now am I the only one that thinks this is an amazing idea? You can use the regular PS2 controllers (with rumble) as wireless controllers without having to buy a third-party brand that is uncomfortable and lacks the rumble features. I don't remember what it's called or how much it cost.
