Wondering how much agreement I would find here with a Petosa salesman's claim that the above instruments are of equal quality and value? I do like what I hear from the am1100, a great sound and well balanced between right and left hands, but have they got as much care and craftsmanship put into them as the Golas? Is the status of the Super 6 exaggerated, mythical? My old teacher had a 45 key Gola with the stradella and three row free bass; I have ever since been in awe of him (now with the angels) and his accordion (now where?).
