For roughly 100 bucks...
Of the ones on the list I've tried the Glenlivet, Lagavulin, Oban and Macallan. Of those, the Macallan was my personal favorite--oaky and very smooth, with a slightly spicy finish; it's exceptional. The Glenlivet is also good--it's much heavier and sweeter, so if you like the sherry cask taste, it would be good for you. Lagavulin is decent if you like smokiness, but there are better options at this price point if that's what you're looking for. I was unimpressed with the Oban--I am generally underwhelmed by any of their offerings, though, so it may be personal preference.
