I'm 25 hours in and only managing 2-4 hours a month so very jealous of the 2 hours a week brigade. I 'm loving it and did my first solo in May. I started at Perth with leading edge, I have changed scools and now fly with Border Air out of Oban, their instructor Graham Dawson is first class. I did manage to fly my plane down to Leeds and back earlier in the week though so got 6 hours flying and navigating as well as dodging thunderstorms done over two days - the highlight of my flying so far. I bought a starter pack and have had good use out of all the kit. I pay for lessons as I get them rather than up front. I found the airlaw book a dreadful read and instead found the Oxford DVD much easier to get through and it got me a pass - you can have it for a tenner :-)
Good luck and I'm sure you'll find PPrune info a great resource, I certainly have. Ian
