I'd like to pick up a bottling that is sort of the classic Bowmore expression - should I pick up the 12 yo, 15 yo Darkest, the old 17 yo, or the new 18 yo?

Locally, I can get the 12 yo for $43, Darkest 15 for $50, 18 yo for $80, and also the independently bottled Bowmore Prime Malt No. 4 1982 (21 yo) for $80. Not sure if any place still has the 17 on the shelves, but Binny's has it still...

(I posted this as a reply in the what are you drinking thread, but thought it would be more appropriate here.)
