You can tell a lot about a mill by its table. This one is shiny and unmarked. It is probably hardly used and suffered transportation and storage damage to the paint. A mill like that, assuming all the lead screws are in in great condition (easy to check) would go for 5000$-5500$ in Alberta.
This one is at a dealer, hence the markup. Not obscene, just business. If someone would come in with 5K cash, they'd own it.
