PC gamepads and PnP

[Rapstah]

I found out the PS3 will take Plug and Play gamepads and joysticks and allow them to be used as Controller One, but I have two questions about it:

1.

Are buttons aligned with their correct positions on the Sixaxis? If the controller I plug in has the same amount of button in the right places, will they be at their right places?

2.

I like the 360 controller, but I also like the PS3 controller, and getting a 360 is out of the question for me, so I went for a scavenging hunt for controllers similar to the 360 one. I've understood the wired 360 controller doesn't work, but how about the Chillstream PC controller;



It appears to have the right amount of buttons. Does anyone know if it's Plug and Play, and if it would work in the PS3?

Thanks.
