I learnt to fly ages ago with the original Sunland with Gordon & Jean Jenkinson and crew, since then I have flown with RQAC, Redcliffe, ADFA and Hemples. I have also flown with the current (Maltby owned) Sunland and have only the highest opinions of Brian Westin and Peter Franks presently at Sunland. If you want to learn on state of the art modern aircraft with quality instructors, then you would not find better instructors anywhere. Just remember it is YOUR money and you need to be comfortable wherever you end up so ask plenty of questions including the instructors experience (you have a right to know) costs vary and depend on the type of aircraft you train on and level of experience of the instructional staff. Be careful of "packages, prepay schemes, airline academies (read sausage factory) and be careful of the frostings some schools promise when you finish your training .
