As only a very recently qualified pilot I am not really in a position to comment on the Hughes300 v R22 debate (and it has been covered extensively in another thread on here). But I completely agree with you that the instructor is more important than the machine. As others have said, there are people at Gloucester who will train you on either. FWIW, my personal advice would be to buy Ray Jones a cup of tea at The Aviator and listen to his point of view...
