Getting ready to purchase a 240V charger for my home. What does everyone feel is the best option? Is there anything in particular I should be looking at? The ones that I am currently reasearching are Schneider Electric EVlink, GE WattStation, SPX Power Xpress, and the Voltec. My main thought is that since I am doing it, I should go ahead and get a higher power output unit in case I get a car a little further down the road that will allow for it... Any thoughts? Is there anything else I should be considering other than power output, and price?
