My intuition tells me that this might be a waste of money, but my intuition doesn't know a whole lot about photography. Has anyone had any experience with this accessory?

I have not much confidence in those fancy solutions (Expodisc, etc.). The cheapest way is to hang a white cloth over your lens :-).
In the field I usually do not need to fiddle with the WB, using "Cloudy" most of the time. In difficult situations (e.g. macro shots in the forest) and if I have no stress I shoot a reference image with my MacBeth color checker and adjust the WB at home, which is a breeze when you are shooting RAW. When shooting concerts or musicals I have a different approach, usually setting the color temp., experience telling me which Kelvin number to use.

Kodak used to sell a gray card that was spectrally neutral, but you can't go wrong with the "X-Rite 421869 Mini Gray Balance Card" available on Amazon for around $37.00 or the one that I use a spectrally neutral plastic gray card "DGC-100" from Robin Meyers Imaging, www.rmimaging.com, for $14.95 for a 4" by 6" size. He also has the "DGC-150" for $29.95 in a 6" by 9" size.
A spectrally neutral gray card will be visually gray under any light source and I have had excellant results with them in my macro photography of minerals.
