We always seek out the cheapest hourly rate
Well it might be true for some, but not necessarily for all.
I try to assess most things by "value" rather than cost - what do you get for what you pay?
I quit using a particular club because I thought their aricraft were rubbish and poorly maintained. I joined a nearby club with better maintained aircraft, and a better atmosphere with interested instructors - yes it cost more per hour, but it was worth it.
Mind you, if you have to scrape every penny together to fly, this isn't always possible, sadly.
