Sound advice, Bmac - just noticed your post after I just wrote the below

I think we're on the same track here...
I was in New Zealand last January (not long enough!), and just on the North Island (I know, I know) - after spending two and half weeks in Oz (Australia). While the Tasmania pinot noir is okay, the NZ pinots are really good, as is, of course, the sauvignon blanc. In fact, there's some pretty good olive oil down there as well.
A really good sparkling wine, if you can find it (it runs about 14 dollars US a bottle here in NYC) is either Cremant de Bourgogne or Cremant d'Alsace, particularly the rose, but the whites are super as well. One of the best deals going. I'm not a big Italian wine expert, but I believe Gavi is nice too (it's a white, but I believe it's sparkling - but correct me if I'm wrong). Here in the US, an up and coming sparkling wine region is New Mexico (believe it or not).
For reds, some of the best cabernet sauvignons in the US are from the Walla Walla region in Washington State (and darn hard to find back east) - Oregon has a very nice pinot noir too, but it's a little bit overpriced. A couple of "sweetish" but still pretty well balanced and good wines, at good prices, are the Francis Coppola ([I]that[I] Coppola) pinot, and the Macmurray Ranch ([I]that[I] Macmurray) - both around 14-15 dollars, a bottle. A pleasant Oregon pinot that's not too too overpriced would be Willamette Vineyards - about 22 dollars if you look around a bit.
I'm not a big fan of Aussie wines, but there are some great bargains out of Chile, particularly in the reds. I'm also not a big Argentine wine fan, but there are some pretty good Malbec (reds) out of there too. One grower - Catena - is really good out of Argentina.
German wines that we have in the US are pretty much all excellent - particularly the sweeter Rieslings (I was never a big fan of the dry rieslings). Austrian wines are really world class too (the whites). They can be pricey, but there's some good ones around 15 to 17 dollars worth trying out.
Like the Italian wines, I don't know much about Spanish wines either, even though, I believe, Spain is the world's largest producer of wine.
Well, the list goes on and on - lots of countries are getting better wine-wise. My thoughts are that you can get some really good wines, red or white, for 20 dollars or under, and, in the case of Chilean wines, even under ten dollars (the cabernets). And, like our headphone hobby, the price can shoot up sky high from there, sometimes, but not always, with a corresponding improvement in quality, and, like headphone gear, the improvement in quality eventually becomes more and more incremental.
Of course, being from NYC, all this advice is directed at those 21 and older
