Right now, none. I am in process of moving my "shack" from a room in basement to a empty bedroom on the ground floor. Have to run 240v to it.
Lucky you. When my daughters moved out I wanted to relocate to one of their empty bedrooms.
The lady of the house gave me a firm NO!
But in reality that may have been a good thing because I would have had to do some wiring in the room. So might as well stay in the basement shack until I can't climb the stairs.
