Personally, I've tried it a few times but I don't have the time to use it so I think it would much more appreciated by someone who is more into this sort of thing as its one hell of a technical workstation.
If based locally (or not) you are free to inspect/try the keyboard and if local obviously you can pick it up without having to incur the delivery costs. If this device requires shipping (and it will be very expensive due to the weight) then we can work out the delivery costs as part of the entire cost. Oh, if you do pickup I also throw in the 'QuickLock' keyboard stand that was 55 quid alone.
So then - offers via PM or thread.
