Welcome, Jeff!
I bought my first arrangers from Petosa music in Seattle. At one time, they were a major supplier of electronic accordions and early arrangers (Soltons-the early versions of Ketron). Bought two MS-60's in the mid 90's and am still using them.
Are they still around? Joe Petosa was a good guy, and a friend of Tony Lovello-one of the original Three Suns (SONS)??-ancient music dudes. Tony ran a hotel I played in the 80's and is still active on the national accordion scene.
