they look nice, gold and silver, but after having dug around a bit it turns out that, being made for safety after all, they are actually lined with thin layers of gold or silver etc... I think the silver and gold often run very expensive.
Please if anyone finds a cheap one, I would love to know
That visor in the link that I posted runs about $40, I believe... It's a lot more than the standard $6.00 visor, but it's definitely a unique item, and cheap in comparison to the prices of most custom helmets owned by members here.
