I am located in Pittsburgh, and I have a used Rostock Max v2 I am looking to get rid of. The printer works great, just needs re-calibrated to level the axes to the bed. The original hot end was replaced with a B3 Innovations hot end, and the original extruder was replaced with a Bondtech extruder. The system also has the upgraded carriages and effector from Seemecnc. I can provide pictures by email, or answer any other questions you may have.
