Why the hell are these so hard to find

I have been searching for one for almost 2 months now - it took me LONG ENOUGH to find a Korg SDD-2000 for a decent price (according to prepal the SDD is worth ~200 and the s950 ~250) - most people on eBay want twice the average price for things (which is why they're the only listings that have been sitting there for the past two months).
And then half the time when something does show up, its from an american who will only ship to the lower 48 states

(and if they do ship internationally, some european will pay $$$ over the average price because they can't get anything over there).
I'm thinking of just buying the s950 on eBay for $360 that has been there for months, I guess it's really only the price of a filet mignon and bottle of champagne over the average price, but then I'll feel stupid for losing money. But these things are very rare to pop up.
Any idea how to find something like this for a decent price? Yes I know of mpchunter - the last s950 was well over a week ago. I don't like waiting. I want one nowwwwww.
Maybe I'll just buy one of the ones from ARMENS for $500/$900
