I have a G27 wheel, I've only used w/ F1 2010 since I just got both of them and I love the wheel. The quality is nice, the steering wheel feels great, so does the shifter. I havent had extended experience on its full potential since my current set up isnt ideal, once I get a good stand, I think it will be even better. The pedals need to be adjusted, since the brake is a lil too far from the gas pedal, so heel-toe isnt easy to do. Ive read you can adjust them, just havent looked it up yet.
The force feedback is insane, you can feel every bump, and you get to adjust it in the game settings.
I also need to figure out how to map all the buttons, if possible, since I dont like the layout of the wheel buttons. The d-pad and buttons on the shifter are perfect though. I'm pretty sure you can change it in the game setting but like I said my experience is limited.
I'm most likely going w/ this stand

lots of good reviews and I like how everything packs down for easy storage
