During my extended test drive, I made sure to learn about charging. I've already found more Roadster chargers than any other type on my routes, and am now interested where I can get a Roadster to Model S/X adapter. Are they for sale new, used, or easy to make (i.e., no logic, just cable and connectors)? I'd be willing to purchase used in good condition from anybody who doesn't want theirs any more.
