...i would go ahead and look for a snell 2005, i'm not sure they if they are out on the market yet but snell updates their standards every 5 years and the saftey guidelines update a year or so later. when this happened when they changed from snell 95 to snell 2000 there were a ton of 95 helmets on sale but the places would never tell you that they won't meet standards in a year.

i guess it all depends on where you are going to use it though, some places are a little more lenient(sp?) than others
