I have a BobaMaker and I love it! Very accurate and expert quality. I also have a bevy of Cruzer items and they too are all top quality. Either maker makes a fantastic helmet. You can't go wrong.
Asok makes very economical screen-cast resin helmets, but I'm not sure if he does fiberglass. Bobamaker makes very nice screen-cast helmets in both cold cast and gelcoated fiberglass.
And as already mentioned, I offer the BKBT Jango helmet in either cold cast or gelcoated fiberglass.
