Scorpions seem great but we really have no track record yet. HJC makes very decent helmets with a good track record. The CL14 is well ventilated and works well.
Ignore the "how much is your head worth" crowd. If you've studied helmets, helmet safety and helmet construction you'll know there is not a correlation between high expensiveness and safety. On the other hand, the Motorcyclist recommended helmets from Walmart are probably not a good idea. You can get a very safe and servicable helmet for under 150. What you are looking for is a second-tier name brand like KBC, HJC, or (perhaps) Scorpion.
