I will second Huntsman's endorsement for the Glencairn whiskey glasses. You can sometimes get a 6-pack of them relatively cheap if you find them on sale at Macy's. It's easier than buying them piece by piece from Amazon and cheaper to boot.
Macy's?!?!? I wish I would have known that. A 6 pack would be the way to go. I might have pick up some more sometime.
