Where can I find a dc to ac power inverter that has a sine wave energy output?

I am using the inverter to hook up a photo studio flash head to a golf car battery while backpacking in the mountains. My flash units are extremely sensitive to cosine wave energy, and thus I want to be sure I am getting one with sine energy output. I tried radio shack, and not even people in there service center could tell me one way or another if the equipment was a sin or cos. Any pointers?
