In that grouping, there are some very good deals on Proseccos out there.

K&L, a wine seller who does a ton of internet business and occasional has some killer prices, has a couple lists of best selling sparklings (and no I'm certainly not saying the best selling are the best out there, but it's what other people are buying). Note that for the French ones, many of those are half bottles. The full listing is here - http://www.klwines.com/bestsellers.asp#29
