If you would like to buy a new wheel and If G25 is too expensive for you, buy a Logitech Driving Force GT. It's a new, better version of DFP and it cost 50% less than G25 and it works with pc too. Remember, If you don't want FF, you can turn it off in the profiler ;)
But... if you don't care about a warranty you can buy a good used wheel (ex. from ebay) ;)
It's my list of wheels which I've tested (from older to newer):
Logitech Wingman (yellow rubber, no FF, no clutch, good pots, no bearing, good shifters) - very good old wheel (photos
here. It's not the same as
Logitech Wingman Formula GP which is newer but much worse.
Logitech Wingman Formula Force (same as above but with red rubber and FF) - very good wheel (photos
here It's not the same as
Logitech Wingman Formula Force GP which is newer but much worse.
Thrustmaster (a.k.a. Guillemot) Force Feedback Wheel - a little weak paddles but it's a good wheel with metal pots and good FF, now unsupported by producer (photos
here, there's a two versions of this wheel with different FF and pedals, I had the older one)
Microsoft Sidewinder FF Wheel - better than Thrustmaster FF, very good wheel with optical pots (photos
here
Logitech Momo Force (see my previous post) - very good wheel (which I'm still using with no problems) - photos
here BTW some people call their
Momo Racing "Momo Force" but it's not true.
Logitech Driving Force Pro (a.k.a. DFP) - see my previous post. Some say it's better than Momo Force. Well... if you want a 900 degrees... yes, it's better but if you don't it's not better ;) Photos

Logitech G25 - see my previous post. It's a great wheel for simracers but expensive.
Oh, I almost forgot about ActLabs Force. It's a great "oldschool-looking" wheel with a great RS shifter (I didn't tested this wheel).
Here you can find an old but good article (it's not mine) about these wheels ;) Well, I know there's a lot of new wheels on the market so if you really want to know something about them, you can always go to forum.rscnet.org :)
BTW don't bother with wireless wheel controllers, especially with no clamp system or mounts via suction cups.
