The VA7 was the turning point for me, I turn to Ketron, The VA had serious problems with the touch screen, the lack of usable samples, the styles too artificial for MY taste and use, it was the Instrument I shortest EVER had, almost 4 months (TOO long).
I am aware that the SHORTEST Roland arranger in production was the EM 2000. Problems with the Screen and not user friendly, I saw and tried a couple of them (some time ago), and I can understand why they cut the production so soon.
Most of the instruments I have had, is for a very LONG LONG time.
From the VA7, I went to the Ketron X1 HD, what a difference, in fact later, when the SD1 came out, I got it too.
I sold Both units ( in my hometown) in 2002 when I moved back to USA. So at least 3 years and some I had them.
For what I know both parties that purchased my Ketrons still use them and enjoy them too.
