I've known about this for ages lol.. only difference between this and the other DFP is that it has extra buttons and a horn.. oh and the FF has been made a bit better.. £119? Spend about £30 more and get yourself a G25!
Not only that, but with the extra buttons the G25 has all over it you can just program one for the horn. I was gonna purchase a G25 and mount my shifter to my chair for realism. *Drools* Mmmm g25.
