Agreed. Wheel vs. Controller is like right hand vs. women. You get the same result, but its a totally different experience.
The dfp is a great choice. Had one for years and I really liked it. After it finally broke down I got the fanatec gt3 RS, and boy, that is an awesome wheel. Especially the pedals, nobody ever talks about pedals. I think they are as important if not even more important than the wheel itself.
Anyway, as I allways say, with a controller its a game, with a wheel its a sim. If you want a somewhat close to reality driving feel, you will not get it with a controller.
Driving with a wheel may be a little difficult at first, but it is soooo much more rewarding in the end.
