Rivet Gun,
Thanks for pointing out my ambiguity.
What I meant was get the licence you need at a flying school and then get someone (possibly an instructor) to sit next to you while you get familiar with your new aircraft. This is legal as long as you are P1 which you will be because you have your licence (and tailwheel sign off etc.) However the other person is there as an 'adviser' while you get used to the aircraft rather than giving training.
Ths way you can own a PFA or Private Cat aircraft which are cheaper and allows you a wider range of aircraft types.
The likelihood is that you will not want a Public Transport aircraft once you have your licence, but you will need one if you want to train in it. Hence my suggestion that you wait until you have your licence to buy something and get some assistance (ie not training) to convert onto it to be able to fly it well and safely.
