Seems to me that a basic trainer that doesn't want to disassemble itself in midair or rollover with the merest hint of lateral movement and is easy to auto is a pretty good thing.
Sure, if someone else is paying for it, or if you don't have the talent to complete the licence in the regulatory minimum with the R22 but think you might with the more benign Cabri. Otherwise the piece of paper at the end that says Commercial looks exactly the same and only your bank account knows the difference.
I really like the Cabri, I instruct and think it is a much better trainer, just too bad it isn't priced lower than an R22.
