I'd go DC-DC if there were inexpensive ATX ones, but there aren't afaik.</STRONG>
Or you could buy some C sized Nickle metal hydride cells and make your own 12v battery, or you could use 10 nicads from a hobby shop that are used for RC cars.
What would you consider an inexpensive ATX DC-DC power supply costing? 20 bucks? 60 bucks? 100 bucks?
