Flightpass are a good school, friendly, professional and well priced. The facilities are good and the sim has very high spec allowing much of the IR to be done on the ground saving some of the cost. Exeters a good place to operate out of as the commerical traffic is relatively low so you don't spend so much time waiting at holds, ground or air, but its not far form busier places to practice. I think Mark Anette has left though.
Check out Airways Flight Training as they are also a very professional outfit with a vast amount of experience, flexible and well priced with a friendly club like atmosphere.
