I would suggest to anyone that there's no point in buying anything other than the best wheels on the market. Poor quality wheels lack 'feel' and accuracy and detract from the game instead of adding to it.
An H pattern gearshift sounds great, but the programming for the game only allows a sequential shift so it can't be done. The wheels with gearshift levers are just pull to go up and push to go down sequential changes.
Most 'pro' wheel users would recommend the Momo Force, and I would suggest buy that or nothing. If paddle levers behind the wheel are good enough for Michael Schumacher, they're good enough for me.
