I got my PPL at TG 10+ years ago. I did it by washing their aircraft in exchange for flying and only ended up paying the exam fees out of pocket. This attitude (on their part) really speaks volume about what kind of organization they were/are - all about flying not about the money.
At the time (and I guess it still is) the place is a family business and the family take a lot of pride in having a smart, well run operation that is open to everyone.
Cheers,
Gareth.
