A decent wheel costs $150-200 a good wheel costs $300-500 and if its a Fanatec you get to add the frustration of waiting months for your product to arrive. Then to top it off you will need a stand or seat which will run anywhere from $130 for a Fanatec rennsport stand to $300-400 for a playseats evo all the way up to $1000-2000 for some of the best cockpits withs good monitor brackets.
So at a minimum your looking at $150 for a Logitech Driving Force GT and $130 for a Fanatec RennSport Stand which may take months to get that stand. Add taxes and your talking $300 just to get into a basic wheel setup.
Because of this you are not the minority if you have a dualshock you are the majority. There is also this

Personally I am using a dualshock at the moment but they absolutely suck as a controller and the xbox controller is much better.
I will be receiving my Fanatec wheel on the 22nd which I ordered in mid January and am lucky as there are people who wont be getting it till may.
I will use a playseats evo. But I am a 28 yr old adult who has been saving for this for the last 4 years.
All in all though I am fairly certain that when you drive a F1 car, x2010, or anything on a circle track a wheel is going to leave you in the dust compared to a controller. The only thing that may change that is that now with the sensitivity adjustment oval tracks might not be as bad as they where before.
