yeah it's really expensive. i paid for board, bindings and skins in the end 550. i had real real luck. but i'm missing those parts for bindings for ascent (toe and heel pieces they call it). and for those two small plastic parts i'll pay now whole 100eur. silly

for boots i'll have existing ones for start. they'll do somehow.
otherwise it's worth checking this, sometimes there are good offers
