£150 or $250 around that, is there any good K2 bindings? as my boots are K2 feel it makes sense
Sorry I can't be of any help on K2 bindings since I never rode a board with them, I'm a Rome fanboy when it comes to bindings. But I do have a pair of K2 boots.
But if your you want K2 bindings that will ship outside the USA look at evo.com (not the best prices but usually a lot more stock since their prices are higher than sites like backcountry.com or tactics.com)
K2 Snowboard Bindings | evo
Tactics.com also ships outside the USA but they don't have any K2 bindings listed.
