I will be honest, I just don't trust Ketron stuff since I had those many headaches with the Solton X1 back in the day. Then I remembered the many threads here about how poor the Audya functioned when it was released. You hardly ever hear of problems with the other main manufactures.

Just to add, I know it's a different company but I still have a GEM WK8 and although its in good condition, the thing is falling apart, hardly works well anymore and some of the symptoms were similar to those I had with the X1 (laggy and locking up). Those keyboards I believe were made from the same country so I don't know if there's a connection there or not in terms of build quality & testing etc...

I know that Ketron may have improved dramatically since those days but I just rather invest in instruments that are reliable and well supported. I don't even know if they sell Ketron stuff in the UK anyway.
