Ya, Go for it.
It is really solid and makes a big difference.The mouse it is a bit to get used to as a opposed to the dualshock, but once with the customized setup it is all I ever use. Looks pretty cool. I get a lot of comments from buddies who see it for the first time, most try it and like it, evn after a few minutes - some don't. It has standard game buttons layout right on the side of the mouse, but you can easily swap functions and you probably will for some moves like going prone and such.
