How about a Vesper martini? I make something similar with Bombay Sapphire, Ciroc vodka, dry vermouth, and lemon, but the real deal calls for Lillet. I like the Ciroc because I think its sort of antiseptic quality adds to the drink, but that's just me.
Otherwise, Glenfiddich 12, if you don't want to spend a lot.
