That is the way that I went with my hour building and very much enjoyed the time I had with the aircraft share, however I did have to a lot of unforeseen maintenance that would have cost a lot if I had not been able to do it myself.
The other problem for the person aspiring to the ATPL is that aircraft shares can be slow to re-sell an this might result in a cash flow problem.
I certainly would not dismiss aircraft ownership as a way to build hours but it is a bit unpredictable on the finical front.
