Keyboard for PS3 (Street fighter 4) ps dont judge.

[Enemi]

So i pretty much started street fighter 3rd strike on keyboard and ive gotten pretty used to it. then i switched to sf4 which is pretty damn good. I like the feeling of the keyboard, but i feel srsly uncomfortable with a joystick and a ps3 controller. Of course its playable but i feel i can do more if i had a keyboard. i'd like to know if someone knows where i can buy an adapter so i can connect to ps3 and also change the controls set up (up down - X button O button, etc etc) or something close to a keyboard because i like the WASD controls. I live in Montreal so if theres anyone who knows where to get it there, please let me know and give me your thoughts about the brand :)
thank you
