Avoid 150/152s like tbe plague. They have too little performance from grass to be worthwhile. Stay safe and use a 172. Start with at least three to cover unserviceablities and once you have a thriving club start looking at something more interesting. More interesting equals tailwheel (Cub, Moth etc.), aerobatic and/or vintage. If people want a fast tourers, let them form syndicates to buy them.
But what ever you do, avoid runway hogs and things with a poor load carrying.
