Based on that answer, I'm guessing that the cheap wall warts are switching? The difference between that and the "big heavy variety" are? Aside from the heavy part :) I thought they all used some sort of transformer to step-down the juice.

IIRC, voltage is a matter of potential, and so long as your wall wart is of the big heavy variety, ie, uses a transformer instead of being a switched power supply, you could just use an 18v or 2x9v's the same way as you would 2 9v batteries. But test before you hook it to anything important :D
