Anyone has experiences with good quality aftermarket shells for the GameBoy Advance SP? I want to buy a AGS 101 model but the condition of the original shell is pretty bad and it seems nearly impossible to get a cheap AGS 101 with a good shell condition. I heard that the most aftermarket shells are cheap plastic and the buttons feel weird. I already have a normal GameBoy Advance with Backlight and aftermarket shell and imo it doesn't feel that bad. But I have no experience with GameBoy Advance SP aftermarket shells.
