Still have mine ( second time around ). For me the arranger itself isn't particularly good, but I appreciate the synth part of it, and it has some surprisingly good panel voices, particularly the organs and analog synth emulations.
It isn't quite as deep as the PA80 for editing, and it doesn't have the wealth of sample rom that the Motif ES has, but for me it still has the most intuitive and best laid out synth edit engine of all my romplers and arrangers, past and present.
It also has nice key action. I remember at the time that it felt to me like a huge step up from the PSR740 I had been playing.
