I have the 740 and have played the 9000 extensively. The 2000 will fall soemwhere in between these boards. I concur about the styles. If simple and pop song friendly styles are required ( such as those a solo performer might use in a live performance ), the Yamaha styles can fit the bill very nicely, but most are 1 and 2 bar variations and may not be desirable for more complex music. I own the Korg PA80 as well and much prefer it's styles to Yamaha's. I have used convetrted styles on both of my arrangers and concur with Tom on this one. Most converted styles require tweaking and still it is dificult if even possible at all to get them to sound as good on my Yamaha or PA80 as they sound on their own board. I like Solton ( ketron ) styles, and have heard some Roland and Technics styles that I like as well. I rate the Yamaha's very high for ease of use and the 9000 in particular very high for features, and both the 9000 and 740 very good for sounds, though I prefer Korg's internal sounds overall a bit better, but that is a matter of individual taste. I don't care for many of the Yamaha styles in general though as opposed to the other arrangers. I wanted to buy a 9000 to replace my 740, but eventually went to the PA80 after a somewhat disappointing run with a Casio MZ2000. I am very happy with the PA80, although it is a bit more difficult to use than the Yamaha boards and still lacks a few top end features that will hopefully be included in the next OS update which is due to be released before year's end. I still want to replace my 740 with yet another board and right now the 2 boards I am considering as potential replacements are the KN6500 and the SD1, although I haven't heard the Roland VA series yet.
