What I found is that to beat the cost of hiring an aircraft I would have to do about 300-350 hours per year regardless of aircraft type. The reason being to offset the fixed costs of aicraft ownership (ie those costs that you have regardless of whether you fly 1 or 1000 hours per year).
Nards .... that is tosh!
Just as an example, my T31m SLMG cost me £2500 to build (they can be bought for around £3-5k). I do the maintanence, which is very simple stuff that anybody with half a brain cell could manage. I'm lucky in that I have my own strip, but if I didn't, the a/c is deriggable and could be trailered to save hangarage. It would be a pain, but if needs must? My total costs for around 75 hours a year work out at around £20/hr. It doesn't drop much for a lot more hours as fuel is now the main factor. A single seat LAA/PFA type might not appeal to everyone, but the point is that there ARE ways to bring the cost down, and to say that you need to do 350 hours to make ownership worth while is just rubbish! I'm sure others will share their costs for Jodel's, group owned CofA types ect ... and they'll certainly be cheaper than 350 hours of club rental at £100+/hr.
