Saw it. Don't recommend it. Note that it's fugly as hell.
It's also made by a 3rd party developer. (I've never really trusted 3rd party hardware products for consoles) Then again that's just my opinion. And where I saw it was actually in a store, not online..
Try a search engine if you need more info, is all I can say for ya. Sorry.
(Also.. this does belong on the PS2 FAQ forum
