I'm in the same boat right now so I found this thread very helpful.
One thing about the dual charger. I decided against it. It was high on my list at first, but the Tesla guy at the store made a good point that I would only need it when I drive much more than 200 miles a day. With the single charger you can recharge a completely dead battery in 9 hours which you always have over night on a normal day. The other point is that 80 Amp chargers out in the wild are very rare. All L2 charging stations are 30-40 Amp max.
What makes more sense is getting the ChaDeMo adapter. There are quite a few out there already and they seem to growing in numbers. Chances you find one of those out on the road are much higher than an 80 Amp L2. And the ChaDeMo will charge 2-3 times faster than the dual charger option.
