Several people have asked me what the differences are between the 6008AF and Integral 2 models, and sometimes people ask about the differences between 6008 Integral 2 and other models.    Ferdi Stutterheim has put together a fantastic table on his Rolleigraphy.org website so all I need to do is point to it.  Thanks Ferdi!    Here it is in case anyone is looking for it...
