It's certainly possible to maintain GA aircraft to a high standard and not break the bank. For example, a flying club I'm in has Cessna 172s for $116/hr wet with no-compromises maintenance.

If you're not directly involved in the maintenance, I am skeptical. For example, many flying clubs only exist because they have members who are A&Ps / IAs, who maintain the plane in consideration of membership. That's a workaround for the problem I'm presenting. I won't say it's impossible, but it's increasingly difficult and location-dependent.

what's the club buy in and annual fee? I instruct out of a 150 and $125/hr is the cheapest I can justify charging.
