Please help with champagne selection...

[pinot evil]

We've tried Cristalino's BRUT but haven't exactly been bowled over (but then again it was $7. But then again it is highly regarded.) If they make an Extra Dry version, we'll try that. At our wine shop, there are many sparklers between $10 - $20. A handful are extra dry. Just trying to save a little money weeding out the stuff we wouldn't like.
Thanks for your help!
