I just paid $1,145 for a 15x9R Flexofold. sam :-)
Chuck, you missed one other option, a two bladed
geared folding prop, like the Flex-o-fold or Gori. With the Flex, you get a
little less sailing performance (it only folds to a width of about an inch but
the hub is that large, so this may be a non-issue) but it has blades with more
curve than a Martec and they have more area out toward the end, so the powering
performance is better and because the blades are geared together, it folds and
unfolds as a unit.
Advantages: you don't have to align the shaft to
assure it will fold - a non-geared unit may have a blade hanging down if the
prop is stopped in the horizontal position - a geared one always has a blade
which wants to fold and bring the other one with it; it unfolds easier in
reverse, so is more reliable in emergencies; and should be available for about
$1000 (it has been years since I bought mine, and I don't know current
prices).
My $.02
