hi all - i'm thinking about buying a driving game and getting a steering wheel (for either ps2 or xbox ... dunno yet). with a controller, i can just sit on the couch and go. but how does it work with a wheel? do i put it in my lap? do i have to put it on a table/flat surface? how do the pedals work? in case you can't tell...i've never bought one before. --- as a side note, if anyone has any recommendations on a particular wheel (including these new wireless ones i'm seeing), or features i should look for, please do so. thanks!
