30-year-old Macallan Dilemma

[Son-o'-the-Sod(?)]

I'm looking to acquire (hopefully in the not-too-distant future) a 30-year-old Macallan, to add to a small collection of single malts. I'm interested in the fine oak or sherry oak, and I've found numerous merchants online offering them in the $750-$1,200 range. Problem is, I need to identify which of the two sherry oaks or the (one) fine oak is the most "limited" of the three (i.e., I don't want to overspend for one that is widely available). So far, I've found the fine oak with a white label (in a blue box), and two sherry oaks: one with a white label and blue box and the other with a fancy blue-and-gold label (large "30" in the design) in a blue box. (Only going by the pictures in the ads.) Of the three, the fine oak seems to be the pricey-est on average, but I can't be sure this exactly correlates to availability. Can anyone enlighten me on this? Thanks!
