Thanks abacus.
I understand where Wersi comes from as I was a Wersi organ user before I moved onto Bohm and Yamaha years ago. As you rightly say, their technology is first class it's just a shame their instruments are so damn expensive and there is little support in the UK. I know some shop in Bolton is supposed to be distributing these now. I did think it was Daniel Watt (think that's his name) but the shop told me he isn't the distributor for them so it's quite confusing to say the least as I spoke to Daniel a few months back on the telephone.
The IKARUS looks to be an excellent instrument and I still may go down that route sooner than later. It all comes down to that one little saying "You pay for what you get and quality doesn't come cheap"
