Recommend me a great scotch whisky!

[brigden]

I'm not a whisky drinker, but I've dabbled in the past. I drink a lot of gin, and often vodka. I'd like to try an excellent scotch to sip and relax with over the holidays. I've been recommended:

Glenlivet 18 yr old
Johnnie Walker Black
Lagavulin 16 yr old
Macallan Highland 1990

Thoughts?

Price isn't a concern, but I would imagine a $200 bottle would be wasted on me.
