Is k2 is good snowboard brand?

Yep. Well... Most of it. Generally in life, you get what you pay for. If you pay like $100 for the three B's (Board Boots 'n' Bindings) its probably gonna be kinda trashy. look up reviews on the boards/boots/bindings your interested in. Good luck!

Yes.. Both are good brands but both are kinda expensive. But I think it's more better to buy expensive brands than cheaper but trashy. I mean it's more better to buy a stuff quality wise than cheap but rubbishy.
