Lots of good ideas from Ghengis, and I think Evo is painting a slightly too pessimistic picture re: renting the shagged out 152... there's a small but growing number of clubs offering smart little 2 seat robins for about the same money. (C'mon Evo! Tsk tsk
)
And if you don't quite make the hours, it's not like the nasty man at the CAA snatches your license away - you just go up with an examiner for an hour and do basic handling stuff. I paid £70 to do that option last year.
