I learnt at Firecrest and got my PPL in June 2010. Honest and friendly bunch. They are not hour- builders and they have other jobs too, so they teach because it is a passion for them.
There is a Pooleys store on site too and a nice cafe so, even if the weather lets you down, you should be able to enjoy the other facilities.
Planes are C152/C172, although I think they have a Grumman now too
Give them a try...!
