Whilst not being glib, spinning the cessna is not really all that much of a drama(Subject to all of the above common sense precautions being taken)
Most interesting spin ever encountered was in an ex BAE Prestwick AS202 Bravo, used to increase rotation rate and do two more turns after the appropiate recovery action had been taken.
With the cessna more or less sorting itself out if you leave it hands off, we should strictly speaking practise the recovery more often so that the recovery is down to us and our proper technique - not the airplane.
WWW did you used to spin the PA-38? is it all that bad?
