More specifically, what is your microphone set-up? Is it on a traditional stand, or a portable headset? Any intellectual edification would be greatly appreciated.

I finally got a Peavey Messenger system, and it has worked gloriously. Be sure to use a dynamic mic, as the Van de Graaff will kill the small electret mics. The system was not cheap, about $500, but it has great sound, is very portable, sets up fast, and works great with both the Tesla coil and the Van de Graaff. Also be sure that you have a good, solid ground for your outlet. Especially with Tesla coils, a poor ground is trouble waiting to happen.
