I use a G29 (EDIT: WHEN DRIVING IN DAILY RACES
... keeping the post on-topic!), which is fine from a bang-for-the-buck factor-- it's fine quality and after you get over the notchy on-center thing, and the notchy feel of the gear drive, serves the purpose well. but I do think I've tapped out what I'm able to do with it, with the available feedback and braking feel.
Yeah, this is the video I watched (after already committing to my wheel...) and it was really interesting. I haven't tried to play with the DS4 since, but I should give it a try to see how close I can get to my current best times. Maybe I'd even be faster on some tracks?!
