KN 700 was my first. I thought I would have a stroke learning and then operating it.
PSR 5600 - loved it
Roland E20 - Very rudimentary and styles way too repetitive...but I used it in combination witht he 5600 because I liked several of the voices
PSR 740. Loved the styles and most of the voices...but punching in codes drove me nuts.
PSR 9000. I loved it. My back didn't
PSR 2000. Only one complaint. Lack of onboard storage.
PSR 3000. Due to arrive tomorrow.
