This is the primary reason of Roland's decline in the arranger market - although Roland restrict E-series sales to the few and far between CK dealers, and give them regional exclusivity, they do not mandate that these CK dealers carry them!!

Roland ought to allow their MI stores in any region to carry the E series line if the regional CK dealer refuses (just forbid them out of region sales). That would solve the problem, and make these great arrangers as widely available as they used to be..........
