$150 and no lower
A 3D printer that I've had for a couple years at this point and haven't used it much since I lack the know-how to get this thing working flawlessly for more prints.
The reason I am listing this at $150 minimum is because I am including not only the stuff that came with it, but also extra springs for the bed, a Creality auto-leveler kit, and a roll of sealed filament.
