For any folks around Chicago, I wanted to offer a recommendation if you need assistance in getting 220V power for your Tesla. The guys from Kapital Electric (Kapital Electric - About Us) did a great job getting a new line out to my detached garage. It was a relatively difficult/complex job given the age of my house (115 years). I got bids from two other companies (including Mr Electric), both of whom more or less balked at taking on the job. Anyway, if you have a complex (or simple) job, I think these guys are great.
