Found this today for sale on CL in the general area of Richmond, VA. Good deal for someone in the area that is looking for a solo weekend fridge for cheap. Too bad I'm on the wrong coast or I'd be on this like white on rice..
Engel 14 f portable fridge and freezer - $150 (Amelia)
Keeps things really cold for an extended time and is very energy-efficient. Runs off cigarette lighter socket in car or similar socket in battery jumper.
Retails for around $650 new. Works great; aside from slight wear on interior, in really good shape.
I live in Amelia but can meet you in the metro Richmond area on 24 hours notice.
