Used Rostock Max V2 Price?

So I have a Rostock Max V2 printer that I haven't used in a while and am looking to sell. I have no idea how much I should list it for and hoping y'all can provide some insight.

The printer has been upgraded with an e3dv6 hotend, an e3d titan extruder, capricorn ptfe bowden tubing, PEI coated Al bed plate, borosilicate with one side garolite bed plate.

I realize printers have changed quite a bit since this printer came out and deltas are not as popular as they once were. Is it even worth listing at this point? thanks for your help.
