Personally I would always chose a single malt, and as such I'm not an expert in blends. That said, plenty of people tell me that blends can be pretty good, so I try not to judge them too much - although truthfully I do think of them worse objectively as well. A great blend might be better than a poor scotch, but I think the worse and best of blends are lower than the worst and best of scotches.

Check out Dewars White Label - http://www.epinions.com/reviews/pr-Dewars_White_Label_Scotch... One of the better blended scotches I've had.

Granted it's pompous but if you're going to spend the money a single malt is probably a good investment. Stop by a quality store and they'll be able to pick one out to fit your tastes.
