Four in an SF260? You're joking, right? It's a great 2 seat tourer with room for baggage but a lot of money for a family ship.
Bigger Cessnas are good value for money in the class you are looking at. Don't be put off by what you think you like now - you'll be surprised how quickly you can get used to things like wings in the "wrong place", lack of a "proper" throttle quadrant or toe brakes.
Maybe a 2 person share would be a better idea - get you more aircraft for your budget without overstretching yourself.
