This is what I do with mine. It has the great advantage that I can kick people off (and have had to do so) without fuss.
In the end, the operating costs have to be recovered somehow. They ALL have to be recovered from the people (or corporate bodies, if applicable) who fly it around. So, different structures (pure rental, shared ownership, various levels of fixed monthly payment, etc) are just different ways of shifting the money around.
If one has a conventional syndicate of X members, each flying Y hours, the cost to the individual member has to be the same as having Z owning the plane and renting it out to X ordinary renters.
So what does that leave us with? I suppose it means that the whole reason behind syndicates is that a lot of people prefer to keep the option of flying very little, or perhaps a lot, while dumping their responsibility for maintenance (scheduled and otherwise) onto somebody else
