Closeouts is the way to go. I would go to a dealer and try a bunch of different brands on and see which fits you best, then go online and find some on closeout. I got my arai for like 380 ish or something like that about 2 years ago on closeout when it originally was almost 700. The dealer down near me has a ton of shoei TZ-R on closeout for 100 bucks! I would grab one but they don't fit my head right.

Thats what I would buy if I were you, assuming they fit you right
