My current thought is to get Dahon 16" (Picollo, $280) or 20"
(Boardwalk, $250) from Aircraft Spruce. While price is not a
determining factor, I would rather pay $280 than $800 or more.

Probably more than you want to spend, but I've been very happy with the
"Bike Friday" I've had for 10 years or so now. Think the cost was
around $500 at the time. High quality, seven speeds, fits easily in the
back seat of my Skyhawk. Won't fit through the baggage door though.
