It IS in MINT condition. e-mailed back and forth with the Dude a few times. Finally, this morning, we talked on the phone. He explained why he was selling it and that they used it about 10-15 times. I asked him if he was firm on the price and he said, "no, why don't you make me an offer". So I did, and he accepted. I told him I live an hour and a half away, and I'll come look at it and if it's in good shape I'll buy it.
Holy crap! The table top doesn't have nary a scratch on it. No sawdust to speak of in the nooks and crannies,and it purrs like a kitten, the nickel didn't budge. I bet it doesn't have five hours on it. He showed me the receipt and it was dated 2/7/17.
Now I have two EX-21's. One for the basement when it's cold outside, and one for the garage when it's nice out.
A special thanks to Bruce for posting it
