I have a pretty good collection of helmets for both bikes and cars. The one most important piece of advice I can give is to never buy one you did not try on. Heads come in all different shapes. Some helmets fir different shapes better. I have an "Arai" head, longed fore to aft than wide.

Beyond that, price pretty much dictates quality of lining materials, which really doesn't affect comfort all that much. It will affect longevity, though. If you wear it a lot, it makes a big difference in this. One quality helmet will outlast several cheap ones and be cheaper in the long run, especially if you wear it a lot.
