Hi Everyone, this is my first post on this forum forgive me if this question is in the wrong section

I have a very good condition EMCO PC Turn 50 Lathe with operating PC, tablet etc that I am thinking of selling to fund a CNC Mill having just purchased a manual Lathe.

The EMCO was given to me as an upgrade had been purchased at the college where I work, my question is how much should I be asking for when I come to sell it as I have no idea at all about its worth?

Many thanks, Ken
