Add to that: save your money for a possible CHAdeMO adapter, if Tesla makes one. In Oregon and Washington they are appearing on the highways in droves. I would imagine a CHAdeMO adapter would go straight to DC, skipping the on-board chargers in the same way as the superchargers. (That's going to open another Can o' Worms(TM), on its own... ) Note: this opinion is based on pure conjecture, and I'm happy to be educated by someone who knows more about Telsa and CHAdeMO. Other than Tesla has been officially mum on it, and unofficially very very down on it.
