I’ve had the $80 Behringer and Dayton calibration mics in my “save for later” Amazon cart for over a year, and jumped on this, thinking a cheap Audyessy mic might help me achieve my goal of World Audio Domination, but apparently the word’s gotten out. Those “cheap” Audyessys now run $75-$100 (with shipping) on eBay and are sold out everywhere else.
