Tecomec Hedge Trimmer sharpening adapter

[computeruser]

I seem to remember that a couple people on AS were full- or partial-line Tilton Equipment dealers, so I thought I'd throw the question out here:

I'm thinking about getting the TL177 hedge trimmer sharpening adapter for my Oregon511 grinder. What would one of these adapters go for?
