What about the 661 Strike 2008 Its from the UK don't know how they pay to send over to American/Canada http://www.chainreactioncycles.com/Models.aspx?ModelID=24917
Fox Rampage should fall right into that price range and its a great helmet, nice padding that doesn't fill up with sweat or anything. i only payed $50 for mine, but i order Fox direct. probably around $80-$120.
For a full face helmet you should deffinetily not cheap out on the price. I know it sucks to drop 80 or 100 bucks on a helmet... but safety comes first
you won't even be able to find a helmet that RETAILS less then $80. unless you go to wal-mart and buy one of there plastic ones, but there all kid sizes probably and won't fit.
and when i said 8-100 bucks.... i ment euros sorry. Becuase thats what he said he didnt want to pay for, for a helmet. 100 euros = roughly 160 bucks canadian
