Help me get bindings for my brother

yo what up guys. so i got a pair of some older k2's laying around in my basement. Im trying to give em to my brother because i have no use for them anymore but obviously i took my fks's off and put them on my current skis. anyways, im trying to find a basic binding for them so my brother can start to get into park a little. I dont want anything too expensive obviously because he's just getting into it, but i would like something that could somewhat take a little beating around the park. i hope thats enough information for yall. I dont know too much about bindings so i figured id post a thread. yew
