When I was hour building, I looked at all the costs and I decided, that it was much cheaper to buy a share. Ive currently got a share in a C172 and inclusive of landing, it costs £72 per hour wet. Although there is a £50 per month fee on top of that and the initial share price of course. Good thing is though, that once your done with it, you can sell it on, so works out cheaper in total than hiring from a club. Availability is much better aswell.
