Still no luck finding a suitable $2.99 AC adapter in thrift stores; most of the high-wattage bricks are for laptops and put out 19V.

But Verifone Omni 3730's (clunky old credit card readers with small integrated receipt printers) take a 9V 4A power supply.

So at least there's hope of them eventually showing up somewhere for cheap...
