well, dfp is good enough... but for me it isn't as good as G25, and i do, however, have the dfp =)... (just there wasn't the G25 these days, when i bought dfp)
the main problem in dfp is that it's hard to rotate it fast =), no matter if there's force feedback on or off... =)
u can buy it if u want save some money, but i'd recommend to look at G25, to try it =) it's real monster =))))) (you'll see what i mean, when u try it) =))))))
