I would think if you want it cheaper your going to have to machine it your self or order 100 of them made and then sell 99 of them :crackup:
$10.00 for a custom anodized part is a bargain and if you don't think so you should try looking in the yellow pages under machine
shops and see what they get an hour to spin metal
Heck the next time your in Micky D's you'll spend $9.99 so just tighten up the belt and go for the cool blue focus adapter
