Champagne (OK, Sparkling Wine) Recommendations for New Years

This assumes you care what it tastes like?  If you are only getting something to fill a glass, buy what ever is cheapest.  But assuming you actually want to drink it....

Under $10 - Barefoot Extra Dry.  Odd think about "Extra Dry" - it is actually a little sweeter than Brut - however the rules for labeling sparkling wine allow a wide latitude in sugar levels, so it is fairly hard to actually know what you are getting without trying it.  Barefoot Extra Dry is just a touch sweet - really I consider this a dry, very slightly slightly sweet, fruity sparkling wine.  It tastes great with food, and it's fine by itself.  I bought four cases for my daughters wedding ($7.49 a bottle, Festival Foods).  I was not disappointed.  It was great for the toast, and it was good to drink with the meal.
