I first tried X1 because of Uncle Dave's recommendation. At the time there was a dealer in Dallas. I drove there and came back with one.
It sounded SO good, but I didn't like the positioning of some of the controls. I kept it about a year and sold it.
The SD1 I bought without trying it first. Loved most everything about it, but quite a few things were getting outdated, especially the Operating System, so I sold it after a year or so. Actually a year is a long time for me to keep a keyboard.
Then I got a Midjay and controller. OS was much better, and it had many great features. Still there were both advantages and compromises with a module.
I look forward to the introduction of the Audya, but I will absolutely have to try one at no risk before seriously considering the purchase.
I doubt the Midjay II will be much different from the original, but who knows. Can't see me going back to a module unless it is really something special.
I don't know the answer to the Ketron distribution problem, but I hope there is one, and that they find it.
The reason I want Ketron to be successful is that nothing else I've heard sounds so life-like and "LIVE". Sure, the other brands all are wonderful, and I find a lot to like about Yamaha, Roland and Korg. They are all gaining ground sound-wise too, especially Roland. However the total package for me is:

1. Sound
2. Features I need. These include vocal processing, harmonizer, storage, screen, controls. There will always be compromises in some of these areas, regardless of the brand.
3. Reliability
4. Weight
. . . and Weight probably shouldn't be that far down, because it is a deal-breaker if it's over 30-something.
