This isn't exactly a board-level EMI measurement, but along the lines of slightly unorthodox methods of working: I have used a piezoelectric barbecue lighter, with the gas canister removed, and the cover over the electrode at the tip cut off, as a cheap and (very) uncalibrated source of esd. It works to test a circuit's response at a very basic level, and is a lot less expensive than a Schaffner NSG 435 gun.

For example, one person I know uses a paper clip to measure radiated EMI from a microprocessor chip. I'd like to include techniques for measuring EMI anywhere within an enclosure, but not outside an enclosure. That's the domain of regulations. If you have any techniques that you'd like to discuss, please e-mail me. Be assured that I will not publish anyone's name (or any company's name) without permission. Thanks for your help.
