Southport-rigging had a swap meet about this time last year. I don't see this year's info on their site. They sell beginner/intermediate gear also. www.southport-rigging.com/
The Evanston Swap Meet happened in the second half of May last year. They haven't updated their 2014 calendar yet.
There are 2 modern Bic starter boards (Nova and Start) on craigslist in the Madison area. I usually search with this...(windsurf|windsurfer|windsurfing|sailboard)
