When I was mulling over whether to buy a Yamaha PSR1500 or a Roland E60, I defintely considered all the 3rd party support I would be losing if I purchased a Roland. I would lose the sweet flute and sweet soprano sax, my favorite styles. I emailed Roland asking who would sell the E50/60 and they never replied, but they replied to someone on the Synthzone. When I found out it would only be carried by a dealer 160 miles from Toronto, Yamaha got the sale.
