THe 9000pro was the most complete arranger I've ever seen....if you didn't need speakers or small size. In terms of bugs ... I don't remember any that were major, and the hard drive was easy & cheap to do yourself. Size & silence were the only things that kept it out of my road rig. The effects section is as good as many home studios, and clearly better than any other portable keyboard. If patterns are your thing - the vast library from all the other manufacturers is available as well.
