I'll be getting my S in a few weeks and need to figure out my charging solution in the interim. Since my S will be parked outside I'd like a permanent charging solution like the HPWC instead of using the UMC out in the elements all the time. If anyone is looking to upgrade your HPWC to the gen 2 and want sell me your gen 1 cheap, let me know. There is a 30% tax credit I qualify for if I buy new so it'd need to be priced <$275 for it to make economic/common sense to buy used Gen 1 over new gen 2.
