I'm selling my used Ender 3 v2, and I've upgraded the hotend, extruder, screen, and bed. It comes with 25 extra nozzles, the old glass bed, and whatever else goes with it (e.g. I can't remember). Is $200 CAD a reasonable price, with delivery?
I'm in the same place as you with my Ender 3+parts. I've found it's not worth trying to list as anyone in the market would just consider a better one.
Have you thought about donating it to a school or library? It would get a new life and you could deduct it on your taxes.
