8x10 Fujifilm Provia 100F at B&H is only US$11.00/sheet, less shipping. And 8x10 E-6 processing at, say, E-Six Lab in your own Atlanta, is only an additional US$6.00/ sheet. No shipping as you could likely deliver and pick it up yourself.
That's only US$17.00/sheet. Not inexpensive, to be sure. But if you already own an 8x10 camera and don't have a 250-exposure motor drive attached to it, that's not really very much. Especially just to be able to say you've done it once or twice.
I'm considering giving it a try when we have our annual 3-week summer and the rains momentarily pause sometime next August.
