Hey! My first post period!
Like the last guy said, there will be some break-in period if you've been using the keyboard forever. I think you'll find yourself smiling a lot and having much more fun, and a much more immersive experience in general with a wheel. I have two, a super cheapo non FFB and my Logitech Momo Force (that I actually use now) and I could -never- go back to any other controller. Dual analog controllers (forced to use it when doing Toca 3 in split screen) work better than I thought, but there is still no comparison. If you like driving games, get a wheel when you can afford it.
Cheers!
