Playstation Pad Grip/Battery

They're only available now in China but it looks like a great concept: A battery pack which clamps onto the PSP which provides Palystation Gamepad-like grips!

The unit provides 4-5 additional hours of gameplay. The PSP Blog indicated that some users reported the unit was leaving scratches on their PSPs... so let's hope someone else comes out with a better mousetrap here in the States.

The grip/battery thing sells for about HK$200, which is roughly $25 US.
