Looking to buy one, but I was wondering will it connect straight to the pc or what will i need to buy?

It's USB, just plug it in.

Yes, just download the Logitech profiler, do not let the PS2/3 compatability fool you of its ability to play with the PC...its just a USB straight plug in...then download profiler, or if that doesn't work, you download the MOMO something or the other, and adjust it in control panel...

I bought mine on Ebay £69.98 inc. Postage and Packaging
