Hi Luke,
Bear in mind joining / membership fees - Donair's is about £90pa iirc? When I contacted Leicester recently about joining (for cheaper hourlies) they quoted me £350pa, plus £50 extra in year 1.
That's a *lot* of £10ph to claw back.
My advice - stick with Donair... you're already there, you've got the benefit of full ATC at EGNX, the club's good and don't rip you off, and Leam / Jag /Ade etc. know their stuff as instructors.
Have you thought about asking your parents to block book 10 hours at a time for you (if they are able to?) then you pay your parents back at a cheaper rate than paying the full price at Donair?
Maybe see you there some time
