It looks like it is hard wired into the electrical. It would be easier to sell if it were on a plug. But this way a buyer should at least be able to turn it on and see it run. In my book, that is a wash as far as the price. If you have to hire an electrician to disconnect it, that my be a factor too.
There is some surface rust visible but I can't tell how the rest of the table looks. Please post many pictures here, the more the better and close up details of a few things like the surface of the table.
Also there appears to be a DRO (digital read out). Try flipping the switch to see if that comes on. That is a plus for you if it works.
In my part of the country that is probably a $2500 + machine. In TX I suspect the $2500 to $3000 is a valid estimate if it runs and the DRO works.
Accessories just add to the price.
See if you can find a tag that shows info about the motor. HP, phase, voltage. That kind of info will be important to a buyer.
A year ago, I would have been contacting you about buying it. I drove 3000 miles round trip to get a mill.
