Hi shane,
it is a very personal choice as stated because fit is what is most important and we all have differeny shaped heads............apparently
My last three helmuts were Arai, HJC and current is a Suomy Trek which only cost me $318.00. Wayne Gardner imports is the importer.
The Suomy fits me really well, I think the best thing to do is just to shop around, a cheapo helmut will be just as safe but may be a lousy fit, may be very noisy or have poor vents or a crummy visor fitting.
My 2 cents worth, but ventilatioon is a big issue here in Summer.
Good luck,
Davem
