Agreed. My former advisor was as good as anyone in that field. He has a very good introduction (... for a grad course in physics) to the dynamo problem (aka.: the solar cycle) at http://solarphysics.livingreviews.org/Articles/lrsp-2005-2/

It is fair to say that solar dynamo modelling has not yet recovered from this four-way punch, in that nothing remotely resembling concensus currently exists as to the mode of operation of the solar dynamo

From the Brief historical survey, which is at least partly readable.
