Hi all!
I have a used, but well taken care of Vermont Waterways Paddle Adapter for the Concept Rower. I used up the original cord, but I have new replacements for it (not from VW). Religiously oiled and everything is fine working order. Bought it last year, around June 2011. Replaced the wing nuts with standard nuts (easier to secure with a racheted socket wrench).
Will post pictures up soon, so this is just a feeler post at the moment. Link from where I purchased it from:

Thank you!
Nathan
