The real issue with machinery prices is availability ... in Ohio and all around the north/central part of the country machine shops were one every block, supporting a LOT of manufacturing industry. As manufacturing has moved off-shore, the old shops closed down; lots of surplus equipment available at auctions.OK, that's about housing, but what about the tools? Mills, lathes, etc? If peeps are moving in as fast as housing can be built, I would thimpfk that the price of tools would go up in TN and down in CA. Tools are reasonable in Illinois and Michigan because the glut from the car manufactories is still there from 30 years ago.
Arizona does not have the history of manufacturing with all the supporting shops, so not as much equipment available.
