I've owned three system 11 games. High-speed, rollergames, and whirlwind. Whirlwind is by far the best out of the three and the only one that I still own. I also own TAF and like WW better. I'm not surprised that the price on the game has increased quite a bit over the last couple of years. Hard to find a nice one sub 3k these days. Almost sold mine a couple years ago. Glad I didn't.
