I'm picking up my new toy in the next week or two. It's got dual chargers, so I'm looking to use the HPWC at home, and keep the mobile connector in the car w/me. I'm not 100% sold on the HPWC, because of price... I want one, but $750 is a chunk of change! I know I won't charge w/both chargers at the 40 amps, but... $750 is a chunk of change! anyway, any market for used ones? or not needed ones? or accidentally installed ones?
