If you have a 120V to 12V step-down transformer you could wire that as a bucking transformer... basically connect one 12V lead to one 120V lead, connect a plug across the 120V leads and connect an outlet to the 12V lead that isn't connected, and the 120V lead that isn't connected to the 12V winding...you may have to swap the 12V wires to achieve bucking (it will either buck line voltage 12V or boost it 12V depending on how you connect it). Google line buck boost transformer circuit to see a schematic before you wire it.

Thanks for the info. I've actually thought about getting a variac because it seems like one of those things that would be nice to have around if needed. Can you recommend one that isn't too expensive? (under $100 preferably)
