What`s the lifetime of a Driving Force Pro? I`ve had Logitech Formula Force GP for almost around 7 years and it`s still working fine, but I`m looking for something fresh...
Also, is it worth buying the G25 just for the clutch pedal if I need the wheel for around 2 years only?

) then you should have no problem matching that with the much better built DFP. I'm using a DFP (with Frex GP) and my FF GP pedals to give me a four pedal setup. You could always try finding another old wheel to use as a clutch pedal, buying a cheap knackered FF GP with working pedals off ebay shouldn't be that expensive.
