Good news, there's lot's of options for the PS3. Bad news, there's lot's of options for the PS3.
I've only used the Logitech DFGT, Fanatec GT2 and Fanatec CSR-E. Honestly after using the Fanatec wheels, the DFGT feels rather toyish to me. Don't get me wrong it's a decent wheel, but the pedals are bottom of the line.
Lot's of people swear by the G25 and 27, the pedals on the 27 are better quality and can be modded to suit.
I really like the tuneability of the Fanatec wheels and the feedback you get from the CSR-E is 👍 I use the CSP pedals and really like them. They feel much more like actual car pedals to me. And you can adjust how much throw is needed to work a pedal and also swap springs (with the add on tuning kit) for tension.
Fanatec is coming out with a PC/PS3 wheel, the CSW, it's inner workings are similar to the CSR-E, but without XBox support. It will also have interchangeable rims. It's not hit the market yet however.
The Fanatec GT2/3's are good wheels too. Not quite to the level of the CSR-E and some would say not to the G25/27 level either, but nice wheels nonetheless. Paired with the CSP pedals, make for a nice setup.
What drew me to the GT2 and CSR-E is XBox support. My brother and I do some racing on it and I really didn't like swapping setups. Not to mention the MS wheel is not good.
Thing is with wheels/pedals is, if you ask 10 people you're likely to get at least 5 opinions
