Two that are at the top of the list right now for myself are:
Ardbeg 27yr Cask Strength (Laing) &
Port Ellen 1980 Signatory
I wish these were cheep as I'd buy the worlds stock, as is I'll have to save my pennies just to savor them in oz form at my favorite watering hole. A more reasonable whisky that I'm REALLY enjoying is Kilchoman summer 2010, quite possibly my favorite from last year.
