I'm a prospective Model S buyer and trying to plan out how I would charge it. With today's changes in their charging options, you only have the option to get the High Power Home Charging package for $2700 for twin charging and High Power Wall Connector. I don't think I have the need for a High power wall connector. Is the twin charger worth it? On a slightly different note, I got a new garage built last year with standard outlets. Is there any benefit to paying an electrician to bring in 240V outlet? Just trying to plan ahead should my driving habits change as well as resale value. I'm not sure what questions to ask my myself for these issues.
