ive got an Aussi brand and their wakestyle board (c avatar) and its great
i ride very onshore X shore but getting out is easy as. just jump on and ride it with out your feet in until your in deep water/ far enough off shore it takes about 30 sec to get them on and pulled tight.
i dont ride off the beach cus i dont want to chip my board on the reef and also you get pulled about a bit and your pants get wrecked.
the Catapult bindings are $350 and offer huge padding underneath.
they are a very tidy package and make board control that much easier.
not that heavy either, carbon fibre base plate i think (looks it).
i havent found any chaffing around my ankles like that is often complained about by Liquid Force Union users
check out www.catapultkiteboarding.com for contact details and some photos are here




I am a bit biased especially as they are the only bindings i could get in my size (14.5US). so if any one out there has massive feet just email them and they can get you a custom pair.
