The Wine Thread

I have been looking to get a few nice bottles of wine, trying to expand a little bit, and have been shopping around for quality and also value.
Got a question for the Champagne people. Taittinger seems to be a value play, considering the Brut Millesime 1990 vintage is around $100. How is there stuff? Would it be better to get a younger vintage from Pol Roger, Krug, DP, Salon, Delamotte ect..
