Just posting this in case someone might be interested. It's real tempting even if just to have a spare head laying around, they're easy enough to rebuild. He said he couldn't *see any cracks but of course that doesn't mean there aren't any microscopic ones. The shipping to me in OK from NJ was only $40 and the starting bid is only $20. In case anyone wants an extra head for cheap.....might be worth looking into.
