Get the one that fits and feels the best. Every helmet from the $10 xmart to the $150 lbs model meets the same safety standards. Price differences will occur based on weight, vents and fitting systems. I ride a Bell because it felt better to me than the Giro, which were my two lbs options. To me, Bell was rounder while Giro felt more ovalled. That said, some prefer the Giro. Find what you want at an lbs or other store and then buy it on line if money is an issue.
