I have it. although I dont have the official DR or SFA3 ones, this one is pretty good. The sticky pads on it might be crappy, but I am sure you could replace them by yourself. but this one might be different with what I have, since the one I have is in a package with 3 replacement analog sticks.
FYI, I bought mine from sucess-HK 2 months back. They got a higher shipping charge, but the price is only $3 or something. I got two shipped for about $13. And they have them in stock. So if you dont want to wait, you could order from them, just a few bucks more (I could ensure you the great performance)
