Congrats
On a more positive note than 28July2001!
Nice one - just get in the air when you can afford it! I can't think of any reason why any lesson should cost you £200 (go to another club/airfield if Newcastle does charge that!).
You also don't need to shell out for fancy Nav kit like a GPS! DI, map and stopwatch have worked just fine for nearly the last 100 years. If you can't Nav without a GPS around the UK you really need to take a long hard look at yourself and what you are doing.
Crack on! Enjoy the flying.
