DFP's work for the PC too. They have a USB cable so you can put it in the computer and with the right drivers, you can use it. I'd go for the DFP because it has 900 degree steering, giving you a better range of rotation selection. It has more buttons too which I find very convienent.
Though if you do have the money, I'd say go for the G25. Or you can buy the DFP and then get S2.
