Found a new, less expensive source from BrianK on Boxerworks:
http://www.2kracing.com/Product/4426.html
$12.99!
I will give you a critique of this one, first! 

Well, enticed by the price, I ordered one of these and it arrived today.
But I no longer need it, as trolle generously offered to sell me a complete headlight he has sitting on the shelf! Since my chrome ring did get bent a bit, this will be a good way to go.
So let me know if you want the cheap reflector unit. $10 + ship
And I will test fit it with my headlight shell out in the garage to ensure compatibility.
