I have that controller. It's the light Gray one (it looks almost White like the one in that picture though). I can't even remember where I got it (since I never had a PS1, just the PSX), but it's been my favorite Sony controller, actually, my favorite controller period, since. It's a shame the X button and one of the D-Pad buttons need pressed so hard that it's not practical for use anymore. I was going to open it up and replace the plastic things behind the buttons with ones from the original controller, but the screws won't turn, and since I got two Logitech Dual Shock controllers now and use them (as opposed to a converter), I just let it go. I hardly ever play my PSX much anymore. That was my favorite controller though.
