Boy, it sure doesn't take much to get a message active again. I had almost forgotten I had posted this and now I am getting a small flood of messages about it.
Anyway, I would like to add my black anodized aluminum knob to the mix, I bought it from Oscar when I bought the Vortex.
I would like to get $100 (shipped to the US) for the Optipac, Vortex, and spinner knob. I originally bought these three items for approximately $125 (including shipping).
Thank you everyone for your interest!
