I'd primer it, and then CL as a "ready to build fixie". A bit of purple prose leading the buyer on to the chances of creating a great work of art out of a properly prepped frame, and you should be able to get a few buck for it. Definitely include the headset and bottom bracket in the deal. For a couple of bucks of a rattle can of primer and some 500 grit paper (do two coats, sanding in between) you'll probably sell it easier and faster than a bare frame.

I've got one of those drying/hardening in my attic as we speak. Probably will pull it back down around November and start thinking about what I'd want to do with it when the 2011 Velo Cheapo comes around.
