Donny,
I think you should re-phrase your question and ask which keyboard manufacturer has produced a keyboard model that has no record of failure or abnormal operation or released without some bugs/issues in the past year, 2 years or even 10. I would personally love to take a hard look at that board.
There is BIG difference in bugs/issues, and having it FAIL on the job several times a night. I have recordings if you have forgotten. And there was no provision to return and get my money back. Took me two months to sell it. I'm sure the bugs are out now, but it was released prematurely and updates were promised, and promised...but after six months never fixed the problems I was having. Left a bitter taste in my mouth.
I'm truly happy that others have had such success with Ketrons. They sound great and have great features. Not for me again though.
Best of luck to all!
