Tim,
FWIW, you might not have to wait that long. I've been poking around for a new desk chair for the home office & I discovered the existence of used office furniture wholesalers/resellers. Cleveland's got at least two and a quick Google suggests that Indianapolis has at least the same if not more.
Both places here have literally thousands of square feet, rows and rows of chairs - serious stuff like Steelcase, Herman Miller, Haworth that sell new for $600 to $1800 that they're selling for about $120 to $200.
Of course, being used, some of them aren't in the best shape, but it certainly seems worth a trip or two to see what these places have.
