Try the guys at UPR Racing Supply. Their warehouse is in Tucson but they have a great team of folks at Desert Rat just off the US60 here in town. Check the link. This is an open face helmet but they have all sorts available .... yes some are in excess of $300, in fact way in excess! But there are some reasonable options like this one ... I've used this supplier for race suits, helmets, and various lubricants ....
