good and cheap summer helmet?

[MeeLee]

What's an affordable, yet good helmet for summer weather, cruising around town (usually 45mph max, few exceptions)?
Outside temps well in excess of 90F. (90-110F)

One that fits your head in your price range?

The AFX Fx-41 is the most well ventilated full face helmet I've ever worn. It's like wearing a skull cap. It is a dual sport helmet, but you don't need to mount the visor if you don't want it. $125-$140
