I got a good price on a Warthog a while ago and ordered the cheap Saitek pedals (couldn't find anything else in my country at the time). The pedals are prone to some stickiness, but it just feels perfectly natural flying with them.
With twist sticks I always found that I was inadvertently twisting the stick when I didn't mean to. If you're into helicopter sims, maintaining a steady twist on a stick becomes a real chore. It's much easier to use your legs for partial rudder input.
If you're into exploration and heading for a far off object you can sit back in your chair, let go of the controls and simply make small corrections with your feet.
