Thanks everyone for the replies. I'll go ahead and shoot one roll and see what results. However, I hit a better cache of cheap film tonight when I went out to buy some insect repellant at a nearby drug store. Naturally, I wandered over to the film display, and found Kodachrome and Elitechrome 100 marked down to .... get ready for it ... $1.68US per 24exp roll. Also on sale were 3-packs of Kodak C41 b&w x24 for $2.68. I bought everything on display, and I'll be going to other locations of this chain (Eckerd's) tomorrow.
Oh, the insect repellant? For some strange reason (computer glitch?), it rang up as $0.57! Think I'll go back out and buy some lottery tickets!
