there are standards to helmet making so we don't get screwed. one thing to be sure of is make sure it is DOT certified. i forget what the euro certify is but its supposed to be a little better. most helmets have them though. if you buy cheap then its going to be heavy and uncomfortable. i was at walmart and this dude spent over half an hour trying to make a $60 Bell helmet fit right but gave up. my buddy has a fly carbon-lite and you can barely tell you have it on, but its a $300 helmet. there are a bunch of great brands out there but i like my AFX helmet. its a good no thrills just standard helmet with some well placed vents. maybe $60, but $70-80 will get you something you should be happy with
