Talk to Joel at Earth Tools in Kentucky. He runs earthtoolsbcs.com, they have a forum where he will list any BCS item for $20.00. He will also help out with shipping, he has several good freight contracts and will set up shipping between you and whoever buys your chipper. He is the largest and best dealer in the U.S.
I listed a mower with him a few years ago and sold it for asking price, and had no flakes, unlike craigslist.
