well, Hi tech bikes in san diego has like 8 or 9 of them on their showroom floor. dont know where you are located but if your looking for a dealer go to www.hi-techbikes.com

FYI, the Flight looks so nice. very good looking bike, as for the ride quality, not sure. but i tend to go with whatever testrider.com thinks is good. great site and they havent steered me wrong yet.
Cannondale Slice got some great reviews.
also look at Isaac Aerotic
