Got a used DF 500 off Criag's list. It was used in a door shop for a while so I need to clean it up a little. The cord has gorilla glue all over it and it is missing some cutters and didn't come with any domino's bit for $500 I think I did okay. Now I am cleaning it and checking to see what bit is installed. I am excited to order some dominos and give this a try.
