I wouldnt rely on that tundra here, especially not since that bonzo sale indicates that this will be far too high.

The dude that got it for the tundra sidegraded it with adds for a different tundra with a suggestion even lower than the other one:

The misty headwarmer has no possible minis but assuming current (or even assuming its worth no more than buyers pay for it), that means that he just destroyed ~150 keys of value with those two tundra trades :P
