There are a lot of variables, but it usually works out that the "break even"
point between owning and renting is around 150-200 hours/yr. But if you can
fly 100 hours or more, the costs are close enough that the overwhelming
benefits of ownership (predictability, scheduling, flexibility, pride, etc.)
make it a great way to go, provided you want and have the extra time to
spend managing the ownership aspects (maintenance, keeping it clean,
paperwork, etc.).

Below 100-hours, ownership really doesn't make economic sense so I advise
people flying the typical 50 or 75 hours per year to try and find a 2- or
3-way partnership.
