In the UK I understand the problem is that you need an aerobatics harness to do intentional spins and many aircraft simply aren't equipped.
I did PPL spins on a Super-Decathlon and thoroughly enjoyed it. Although the price per hour was high, we spent a high proportion of the time climbing to do the next spin, and had it not had such a powerful engine we'd have spent even more time in the climb.
I did wonder whether it mightn't have been falsely reassuring - having big control surfaces you could enter and exit spins as quickly as you could think about it. My understanding is that if I got a PA-38 into a spin I would have to hold the anti-spin controls for a turn or two whilst the spin tightened _before__recovery, which would take considerably more self-belief.
