I had nothing to do at work today and since it was only a half day I decide to search Craig's List using SearchTempest. Anyway I found a person in Western Mass with a YS640 with the second shelf for sale for $900. I emailed him and it's too big. I was waiting until March to buy one new but this is a good price, unfortunately I have no way of getting it and after checking with carriers, it would cost between 500 - 600 dollars. The second one I found was in Middletown, RI. This is a Yoder 1500 in the comp cart. He is asking $3200. Thought I would just throw this out there.
