Can anyone reccomend a good convertor to use PSX/PS2 controllers on a PC? The reason I want to do this is two fold:

1.) I've had my gameport microsoft sidewinder forever, but the d-pad is CRAP. Thus, it's terrible for any kind of figthing game.

2.) I'd like to be able to play Stepmania/Dance With Intensity with my ps1 pads. Even though I own all the US DDR releases, I'd like to be able to play some of the original fan made song/step patterns and some of the ones that never made it to home consoles.

So, can canyone reccomend one? And a good place from which to order? I was going to order from zophar.net but the ZD store is now closed.
