Same here, after years of DS3 racing I finally picked up a second-hand DFGT last month and have to say it's the best thing I've bought in a while. I got my time down to 2:17.5xx and have watched Tidgney's video on my lunchbreak today so I know exactly when I'm losing the time. Can't wait to get home!
Anyway, back on topic, I researched various wheels and it appears that the G27 is the must-have wheel at the moment, but due to cost it wasn't really an option for me. The DFGT is the perfect wheel for rookies like me and hardcore gamers, in my opinion. It's a tad loud, but I just stick in some headphones to compensate.
