I got two 2008 Boardwalk S1s from Performance Bike for $440 shipped last year. I considered driving to a Performance Bike shop, but that would be a long trip and the tolls will probably cost the same as shipping.

Nice bikes, I took the fenders and rack off one of them and now it can be rolled (somewhat). Wish it has the magnets that keeps the bike folded, I put on some velcro, but that doesn't work too.
