There's lots of options...
Clubs work well... some have low dues, reasonable rental rates, and usually no daily minimums. The time you fly in a club plane to stay current will also give you some time to offer rides to people who are less "experimental" in nature.
Throw in some availability to fly while you're off line for maintenance or annual, maybe a plane you'd be more comfortable in IFR, etc... loads of reasons.
Once you know what "most of your flying" is, how many "need more" flying you expect you can get out the old excel worksheet and find the answer.
But remember, if you're going to go with club/rental for the bigger need flights, fly that plane often enough to be proficient. We're not talking about having smart car and rushing over to the rental desk when you need a suburban.
