For charging, you could plug the EVSE into the car, put the brick in the back along with the little 6 amp battery charger and plug both into an extension cord. Plug in the extension at work and close the rear hatch on both cables
I managed to find my RoadPro used but unused for $20 on Craigslist. In keeping with my "cheapskate" nature I will look for a used AGM battery as well. After all its Spring and I will not need an auxiliary heater till Autumn, so I can keep my eyes peeled. I like the idea of not having to worry about spills or gasification issues.
