Money: I did my PPL in 45 hours (and 45 minutes) and I'd say all told it cost nearly £8000. That includes all of my own kit pre-planned for commercial training (so the more expensive options e.g. CRP5 rather than CRP1 etc.). I did all of my training except for the first 4 or 5 hours on a brand spanking new Warrior III (had about 150 hours on it when I started).
As a previous post says, when I look at at some of the photographs I have now it was worth it. There is more to a PPL than being able to fly. I found it extremely rewarding and I found out a lot about myself and my capabilities doing it. I think the experience improved the way I look at problems and setbacks!
