how much do you want to spend? what din do you ride at? theres not much between most to the high end bindings these days. i've currently got salomon sth 12's and mojo 15's, and have used look px12's and they are all good. you'll be riding mostly park i presume? so make sure you get ones that have metal base plate, ones with plastic will be cheaper but i've personally seen about half dozen heels break because of plastic base plates.
depending on the $$$ and din:
try searching as well there will be a kajillion threds like this.
