Mellotronists

Looks like someone went for the "Buy It Now" price of $3500 on the 
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?
