"$40" microphones?
Some existing opportunities to get a fine used dynamic microphone, at even under $60-$70...
Including shipping cost/etc.
Usual suspects include AKG's D770/D790,/D8000 type series.
Some sound great on used 57/58's.
Also IMHO the Shure SM48 is underrated.
Occasionally for sale IIRC at $40 (or less) at Musicians Friend/GC.
Some nice used condensers come up too.
Besides 3U CM-1's...
SE X1/AKG P120/Blue Spark/Studio Projects B1.
A (previously posted elsewhere at GS) cell phone...
"One take/off the cuff" Practice Vocal below.
It was recorded on a beautiful day outside, on a park bench.
It's part of an old Traffic song I love.
Getting a bit Psychedelic here.

P.S. Originally recorded in glorious Samsung MP4!
