Lobolives, I completely sympathize with your reasons, and share them myself. Your reason #2 is a real practical concern.
As we've said before, it's nearly always preferable to have everything under the hood - keyboard, control panel, effects, and so on, all in one instrument. But sometimes, regarding your present musical needs, you just can't find it in that ideal format. So, you might as well take advantage of the abundance of modules and assemble your own instrument - be it two Odyssey Desktops, two Oberheim SEMs, a combination of the two, or whatever. There are so many choices today, so that we might as well use them to design our own very original set ups.
I do hope that one day DSI inherits the Oberheim tradition. It would be a natural progression.
