With more folks around here dipping their toes into the EV waters this may be of use to someone.
Clipper Creek LCS-20P with NEMA 6-50 plug. Excellent level 2 charger for any compatible EV (check the clipper creek website for compatibility, I used it on an ELR, would definitely work with a Volt as well) works great but I sold my EV. Will ship at buyers expense. Retails for $395, selling for $150
