I already suggested you the one (remember : 9,49 $) but, for me, it's very very sweet. But it you think that the Gewurztraminer isn't enough sweet, I think you will appreciate the Monbazillac.
I didn't speak about the Sauternes because it's a wine of my region, and here, it's less expensive. On this site, I think that the price is very expensive. I suggest it now, because we spoke about this in my family and an half thinks that the Monbazillac is more sweet, and the other half thinks that it's the Sauternes which is more sweet !
If you choose to buy the Sauternes, just know that more " dark " it is, more sweet it is and older it is, more sweet it is. In my example, the wine to 47,60 $ will be more sweet. Me, for the same price, I prefer to drink Champagne.
