Overall, the 150/152 is a very economical plane to fly. And I mean 'economical' in the broadest sense of the term - as airplanes go, it doesn't require a lot of money, time, skills or effort to own and fly one.
They are simple to maintain and repair, but are not 'bare-bones' transportation.
There is a large and well-stocked inventory of new and used parts available.
It's the cheapest 'real' airplane one can buy. Any cheaper and most likely you're talking 'ultralight'. Yet spending more only gets you two more seats. It's at quite a nice price/performance 'sweet-spot'.
And lastly, in all seriousness, this Club. In my very informal polling, I'm finding this type-club is one of the most active around (I'm sure the Bonanza club does more, but the price of admission is steep). The depth and breadth of active, participating and friendly club members makes me enjoy this plane far beyond its physical capabilities.
