Mark Mandell - Gone Round In New Jersey
To the "angry guy": "You have a nice machine. It is the lathe I wish to buy, but if I buy a new one for just a little more, I get a new machine guaranty and won't have to wonder how this one was used. I'm willing to buy used if there is an opportunity for savings. I wish you all the best in your asking price, but if you change your mind before I order a new one or find another used unit, please, feel free to call me."

Then smile, don't offer your hand, and walk away.
