If you really want the most realistic feel to your simulation, you need
to get a wheel. The Thrustmaster is the most sturdy and realistic wheel
that I've seen so far. As far as the wheel-type pedals, I too was
apprehensive when I first got mine and saw those hokey-looking roller-
blade wheels sitting there. I can't imagine why anyone would design the
pedal assembly that way. Having said that though, I must say that they
are very comfortable to drive with, although I have found that the only
way that I can drive effectively is with one foot on each pedal, which
cuts the time required to physically lift your right foot from the gas
to the brake when decelerating, and vice versa when accelerating.
I guess the bottom line is how much you want your sim to approximate
real driving. I paid $230 (Canadian) for mine (taxes up here are ***)
and I think it was worth every penny. I especially like being able to
shift with a stick instead of pressing a button. Also, the pedals can be
used in other games as well. My pedals double as rudders for "Wings of
Glory". IMHO, well worth the investment.
