The Rat3 was my previous one, actually. Despite being a Madcatz product, it was actually a fantastic mouse, was quite surprised with it. Was none too pleased when it eventually died. But it lasted quite awhile. Well, technically it still works, it's the mouse wheel that eventually broke. Have never seen this newer one before. $130 though... pretty high price there.
This entire series of mice look so strange though. I remember shortly after I got it, my cousin came over to my house, and he took one look at it and said "What's wrong with that thing? Did you get angry and stomp on it a few times?"
