From my observation and experience @ Cessnock it might pay to look at the other training school on the field apart from HVA. There are two to choose between and I know which one I would choose.
Go up and maybe do a TIF (trial introductory flight) with each school and use that to get a bit of a feel and go from there. TIF's are not too expensive and are a good way of getting a chance to talk to the instructors and gain insights as to what place suits you. It is normally a discount flight and don't forget you can log the time also!
