Model S arriving shortly, but 2nd vehicle in garage in next year or two may or may not be a Tesla. We want to future-proof things by getting a more generic J1772 (80 amp) vs the HPWC. I'm guessing there are many options for the high-amp J1772 EVSE; is there a go-to piece of equipment people are installing right now for this type of scenario? I'm sure there's already a thread dedicated to this topic, but I didn't see anything definitive after a quick search. Can someone point me in the right direction?
