New, mint condition, paid $185 last winter.
UGG Men's Butte Boot, Worchester, Size 9. ("Worchester" is the Uggs model, not where I am located.)
The UGG Butte is listed by The New York Times Wirecutter as one of the top picks in the "Best Big Spenders" category for winter boots.
I realized I bought the wrong size after the Amazon return window. (I was heading above the Arctic Circle and had not taken into account wearing extra socks.)
Current price range on Google is $140 to $200.
