You have to do the sums and see whether owning the aircraft that fits your mission profile is cheaper than renting it. It's cheaper for me to rent for various reasons and I have looked closely and number crunched ownership or syndicate.
We all fly for different reasons so ultimately you have to decide what the best option is for you. There will always be people who tell you that they paid 3K for a share in a Blogg's Peppergum and it costs them tuppence an hour to run it; but if it doesn't do what you want it to do then it's a waste of time.
