To lump ALL arranger players as
" modestly talented amateurs who lack either the time, the will, or the talent, to learn a 'real' instrument and who demand to sound good with the least possible effort" is just WRONG.
PS chas, if I did not understand your position on this, or misinterpreted what you were saying, feel free to correct me ...
Tony, if you go back and read my post, what I said was that this is the TARGET GROUP of the manufacturers. Many arranger players are fine musicians but they were fine musicians long before they took up the arranger. Even so, I'd still prefer to hear them on their original instrument (even if it's an accordion

).
Ok, I lied. I'd rather hear the arranger.
