I think Backpacker is spot on.
The first thing I did after getting my PPL was schedule an hour of spin training. I had never been comfortable in stalls and did manage to initiate a 1/4 turn spin in a C152 while badly dorking up solo stall practice - that scared the hell out of me. I was apprehensive in the spin training as we climbed and prepared for the spin until the wing dropped and it started to autorotate. At that point, it became the most fun I'd ever had!! As soon as the nose dropped to the left, it became an unmitigated blast!
More than that, though, it removed the fear of the unknown - just what is on the back side of a spin that's so dangerous that you can't do them in PPL training? Answer - not much, really. It's a completely controllable maneuver in most airplanes. In fact, in aerobatic types, you can control the recovery to within less than 90 degrees of an intended recovery point. Spins of 1 1/4 and such are routine maneuvers in aerobatic contests.
After just that one spin session, I was no longer afraid of the airplane falling out of the sky, unusual attitudes didn't bother me, and my confidence in the aircraft and in myself skyrocketed.
Definitely do it!
