I've never been impressed with Dom Perignon when compared to other high end champagnes. I don't think it conpares well to Krug and it isn't in the same class as Clos des Mesnil in my opinion although I think the latter is outside the OPs price range. Another great choice and well within the price range is Pol Roger Winston Churchill Cuvee. Again, I wouldn't hesitate to pick that over Dom Perignon even if the Churchill cost more; which it doesn't.
