My favorite is Krug, and although more than I usually spend the Krug Clos des Mesnil is wonderful. I dont like Perrier Joeut at all I have to say. The Bollinger Grand Anne I have had and some other Bollingers as well I have liked a lot. One brand I didnt see mentioned was Pol Roger. I have had their non-vintage brut a number of times and it is very good for the price. I prefer their premium bottle, the Winston Churchill Cuvee to Dom or Cristal and it is typically cheaper.
