You can find them for as little as $100-120. $150 is fairly common. Plus some online stores still have them in stock.
Just so you know what you're getting, any game listed as a "Kickstarter" version (as opposed to "retail" version) will have an additional 6 sheets of counters, units and overlays, including some that can't be found in the retail version. Note:
none of the "exclusive" counters are required to fully enjoy
Ogre Designer's Edition; they just add a little more to the game. Either the KS version or the retail version may also come with the "ACD sheet", but that can be bought
here as well (and again, just extras).
