It's a very good deal. I have the HRAP3 and modded it with Sanwa buttons, but in truth the stock buttons are excellent. I just had to try Sanwa for myself, but now that I've used both I know that I would have been absolutely fine with the stock buttons.
Also, remember that Super Street Fighter 4 is going to come out on a separate disk, and you can easily buy that for the PS3 if that is where you have your stick.
