Given what I thought of this, what recommendations do folks have for other Champagne for me to seek-out? Please try to keep suggestions under $80; bonus points for under $50. 
2012 L. Aubry Fils Champagne Ivoire et Ebene - France, Champagne (2/28/2019)
– tasting note from memory –
Wow! Color me very impressed. Very dry. High acidity. Packed with fruit and tangy mineral tones. No brioche. Taut without being tight. Deeply regretful this was my only bottle. Gut impression score: 92 - 94.
