After my CH pedals gave out I got the Saitek proflight combat pedals (#2 above). They are so much better than CH pedals I would never go back!
Your feet are placed further apart from one another. You push the pedals with the arch of your foot while a slight push with the ball of your foot works the toe breaks. Compared to CH, these pedals are far more comfortable and natural to use, I highly recommend them.
I still love my CH stick and throttle; together with the Saitek pedals they make a great system and you can really forget about the controls and just "fly", if you know what I mean.
