personaly i really like eggbeaters, my knees are shagged and the way eggs work is they don't 'want' to center them self so it never feels like you fighting the float (i found that with shimanos), they also rule in mud.
only problem is they are useless if your not cliped in and some people have reported that they cause some funky wear above your cleats.
crankbros has just released a new range which includes this beast:
may be something to think about if u want a simple design with heaps of mud clearance...
may be a little out of price range (not sure on an $AUD retail price)
