Why is Cabair so expensive? It's basically a premium product, aimed at future professional pilots, with everybody else paying for the same.
Seriously, do look around at other airfields and other sorts of flying. Look, for example further SE, at gliding and microlighting for example. Don't let anybody tell you that any form of recreational flying is "better" or "purer" than any other. If you have time but not money gliding might for example be the way ahead.
All flying is good, some flying are more expensive than others!
