Great recommendations above, Bill. I like all kinds of Single Malts, going from super peated to non-peated, from highly sherried to Bourbon barrel matured only. There's something to be enjoyed at any region and style, I believe.
Now, since you like the Lagavulin 16, my first thought was the Lagavulin 12 Cask Strength, one of my all time favorites. However, it is almost twice as your budget. Someone mentioned above (just checked, it was
@Saoliver ), one outstanding pour and also a great alternative, is the
Laphroaig 10yo Cask Strength. It is about $75 and it might be the best value in Islay Single Malts imo. It is a fantastic whisky. The only problem is that sometimes it is not the easiest to find in Michigan.
So many whiskies, so little time, LOL!
