I have owned and gigged with the Roland E50 and E80 the BK-7M module, Korg PA1X, PA2xPro, Yamaha PSR3000 and Tyros4. I sold everything but the Yamaha keyboards. If Roland and Korg had the style support that Yamaha has I would have kept them. They all played great, sounded good, and were rather easy to work with. For me it was about style support. But today as I grow older I must consider weight and that would have eliminated the E80 and the PA2Xpro for sure.
