Another factor is whether the club/FBO operates on weekends only
or 7 days per week if the weather is OK for flying. I can't see how
an ASK 21 or DG1000 can be economical if flown only on weekends
and/or is trailered for several months of the year. Still, finding
instructors and ride pilots who can reliably be available 7 days per
week isn't easy. Especially if you want them to work for free ;-)
