first M400S:

Including the straightening of the front keyboard panel that will
probably swell up and make the keys stick at the right side of the
keyboard during humid weather, replacement of the missing knobs and
the probable Sound Sales bodges that will need to be fixed, it could
end up being as expensive as a new MkVI. Any comments from the expert
refurbishers here?
