Welcome to our group!  I previously used Technics KN800, 1000, 2000 and 5000, but have not had one lately.  There are several here who do use them, and there is a dedicated Technics discussion on Synthzone.  You can find it by going to the bottom of the page and looking in the little box there.
I think Technics has a wonderful operating system and very good sounds.  I also like their styles.  
The mic input is just about useless and they always required a proprietary hard drive that was way too expense.  I understand the KN7000 will take memory cards, so that is a big step forward.
