I use AuctionZip.Com to see what might be coming to the local auction blocks.
You never know what might be coming up just across town.
Farm auctions often include a few machine tools.
Most that I been to go above the local market value, but I always find something
to throw my bidding card up to.
Mike check out this site : their classified section has a 20 hp for sale. Then check out the photos of the Meme Steam Museum there in Great Falls MT. They have about any type of steam critter made. http://www.steamtraction.com/archive/3155/
