I blame cruddy old Cessnas and PA28's as the sole cause for me never getting a PPL.
Hmm, that sounds a bit much to me. I learnt to drive in a Rover Metro - bit of a heap, but reliable and did everything it needed to. I think if I said 'I blame Metros as the sole cause for never getting a driving license' you'd think I was mad. I drove it and thought 'I look forward to the day when I can afford to drive something more powerful and exciting'.
C150s and PA28s may not be the most glitzy or exciting things to train in, but they're for training.
I go along to the flying school and out come these beaten up 40 year old heaps and it puts me right off. It's no wonder flying is a declining sport in the UK.
I think if you want the PPL(A) enough then you'll get it. If training in a trainer is so much of a big deal to you then you'd be better not wasting your money.
