Mellotronists

(Or the price of any model used Mellotron)

I catch the sense of apprehension of divulging the current value of 
the beloved instruments within our Group--lest we drive up the price 
for someone wanting a good solid unit, or do some other unforseen 
unduly damage... As uncommon as these puppies are, I doubt the price 
variations are regional (I'd like to see one offered on eBay in 
Barrow, AK "pick-up only"). Streetly or Kean's crew ought to 
interject at this point. A sticky question we'd all like to know, but 
(ahem). I wonder if it's published in some *antiques roadshow* price 
guide list--which would be about as believeable as those dumb rare 
records pricing catalogues, or Monica Lewinsky spending a quiet 
evening at home.
