I would also vote for Surrey and Kent flying club, as what you want is someone who has been instructing for many years and has seen it all before. The last thing you want is to be taught by a 20 year old who learnt two years ago, who was taught by a 20 year old four years ago etc etc etc. They may have 1,000 hours but I can tell you the experience is NOT just hours it is having been in the enviroment for a large period of time that really gives the knowledge. Speak to Roger Patterson at Surrey and Kent. You will like him calm style of instructing with his dry sense of humour. When I learnt to fly I had a different instructor every week which was really bad for my consistency, so try to keep to one instructor.
