Arbor comes with a 2yr warranty. You may or may not care, but they're one of the first companies to be really eco-friendly. Their whole line is designed/manufactured that way.
I had an Arbor Mystic last year and loved the board. Have also demo'd several other boards from them. I haven't tried NS boards, but I highly recommend Arbor to everyone. The Element is a board you'll love and keep for a long time. It's a great choice for an all-mountain board that focuses on freeriding and powder, and will still work for freestyle. Def not a park-specific board. Arbor has other ones in their line for that.
