I installed the DCCDPro Universal controller and love it. Jeff is a great guy to deal with as well.
The controller really doesn't compensate for bad driving, it's more predictable than that. I find the acceleration/control out of the corners and amount of steering into the corners is worth the price of auto mode in itself. Overall, you really get a sensation of a well balanced car... Luckily this crappy snow is letting me play with the actual functionality of the dccdpro under slower conditions.
