Are you married to bubbles? I don know for sure myself but Im told that most dry moscato is "still".
Liquor.com suggests you should consider Trimbach Muscat Reserve?
"Unlike many muscats, Trimbach’s version is bone-dry and actually the only Muscat AOC in France which is vinified dry. The highly aromatic floral nose dominated by lime blossom and white peach leads into flavor so fruity that you almost think you are eating ripe grapes or peaches. Good grip to the very dry flavors of white peach, lemon, flowers and minerals. Perfect as an aperitif or paired with asparagus, melon or smoked fish."
Its a little over budget though. The price has recently almost doubled to $23 but Im betting that youre going to see that for almost anything recently imported. Maybe check that hidden corner of that liquor shop where people mostly buy domestic national brand beers and see if theres a bottle hiding there from last year.
