I owned am SD5 which I bought basic and installed my own hard drive with double sided tape. So if I was to buy one again it would be an SD3 (maybe) since the SD5 is very heavy. But then I remember was I paid for the SD5 and I start think its too over priced. When the audya is released forget it, very heavy and very expensive. It would have to be something very good to get me to buy another Ketron. I miss the MS50, compact, not very heavy, great price point, best sounds, the good old days.
