Here's a little sneak peak of my custom build:

Ouch, MUCH easier modding the 360 version to work on a PS3. Let me know if you need any help (and to repay me you can school my ass at SFIV 360).
Not a fan of the grey though, ordered 8 OBSF vermilion and a vermilion jlf for my SE
You need to "padhack" a pad, like in my pics above. For the 360 -> PS3 you use a ready made Cthulu board.
A common problem with the SE's, see if the problem goes away when you switch to sanwa buttons, otherwise it's likely to be a soldering/PCB issue.
Oh dear... perhaps we should discourage you from using a soldering iron

Pics of mine:
...Will I be able to check that they are genuine by looking at the model number on each button?
Did you add the extra side buttons and the switch that the Madcatz sticks have (to switch the joystick between the pad and sticks and to put the extra buttons on the side of the stick?) hard to tell from that picture.rp2000
