A question for the experts: I'm thinking of picking up one of the annual Port Ellen releases, and I'd like to know which among the 6th through 9th releases combines the best in terms of quality with collectibility (I know, they're mostly all damn good). I would be holding onto this for some years before drinking it. The most recent ones, i.e. the 10th and 11th, are too crazy expensive for my wallet, so I'm looking for value but I'd be willing to pay up for the right one. Too bad I can only get one!!
