If you are going to buy a wheel to test the waters so to speak i recommend at least taking a look at the Logitech MOMO (looks like they recently removed the MOMO from Newegg
)
I would have to agree though that the game may not pair so well with a wheel...i have played Dirt 1 at least and i doubt they have changed a lot on the core game...
Either way you still have a wheel for the many amazing racing titles out for the PC...you'll find something to do with it surely
Actually if you take a look around the Dirt 1 mod community there may be some game tweaks/mods etc out that can make the game a bit more suited for wheel racing
