Yes I agree Wersi are quite expensive, and this has always been the case since the company started in about 1969, however there products in most cases have been so far in front of the competition (And even the early instruments were upgradeable) that people have always been prepared to pay a premium.
Interestingly as the new upgrades have been fitted, the price of the instruments since the new team took over about 2 years ago has not increased, (Unlike most manufactures) so the difference in price between Wersi and other manufactures is reducing, also if you look at the price the original Wersi owners have paid to upgrade to the 2005 versions, this has only been a small amount, compared to the losses made by others who had to trade in their instruments for new versions, (2 or 3 times in some cases over the same period of time) so in the long term the Wersi instruments work out cheaper.
One of the reasons I think Wersi are more expensive then Lionstracs, is because as they were developed in the late nineties, the only operating system available to them was Windows (The open source operating system Linux was around, but in such a limited state that it could not at the time be used as the basis for a keyboard, whereas when the Mediastation was developed the Linux software was more developed and so could be used) which meant paying license fees to Microsoft.
Regarding the apparent bad treatment of a particular customer, it has been well known in Wersi and other circles as well as being featured on many other forums, and if you read all the posts (Including between the lines) it is not as clear cut as it seems.
I myself reserve judgment at present, (Although as it has been going on for 18 months or so, its about time it was sorted) as since the new team took over things have improved a lot, (I have also met them at the various festivals) so am prepared at this moment in time to give them the benefit of the doubt.
