I've raced on eggbeaters for a couple of seasons. They work for me - I can always get clipped in even when it's really muddy. I've found them to pretty durable - I haven't done any maintenance on them (caveat - my 'cross bike doesn't get ridden outside of 'cross season) The first couple of races I did with SPD style pedals (Ritcheys) and I like the eggs a lot better. I think there is a reason that you see so many people racing on them.
