Much like an
Apple I, it's a novelty/museum piece/price, not
 something one would likely play with and burn out.  There are
 plenty of non-prototype systems to let the smoke out of.
 But agreed the price and price of shipping are certainly some max
 values I would imagine. 
 I just can't see having a system, no matter how rare
that one would
 not be able to use.  leaving it to bit rot seems a very sad thing to
 do....
