Nothing cheap and low(ish) performance is going to sell. People would rather have nothing and dream of a supership than buy a lower performance glider. Although lots of people will claim otherwise. Funny thing. Buying an old glider somehow covers the ego. Probably because what you get was once a supership. No fault of your own, that was 30 years ago.

HA! Tell that to the many thousands of hang glider and paraglider pilots out there enjoying flight in their "low" performance, low-cost soaring machines! THAT is the problem: There are much cheaper, no-license-required alternatives to sailplanes these days. And they are just as much fun.
