Have you called Bike Friday? They're pretty supportive even of their used bikes, and are usually great about helping to hook you up with local folks who ride them. Seriously - they'll give you names and numbers of people who will let you test ride.

Also, they have pre-loved bikes on their website (I think I mentioned that in the other thread too). They sell for less than new, they do sometimes have smaller ones, and they come with a money back guarantee, IIRC.
