Ok I searched this question has not been asked.
Im keen to get my REW system fired up and am on the look out for the bare min / cheapest calibrated mic.
I've given up on trying to build my own setup.
The two options Im looking are the Sony ECM-AC2 for 29$ on amazon.
The other option is the Dayton Audio iMM-6 for about 24$
I got all the parts to build my own. Like a 2 pin mic and some opamps. But calibrating sounds daunting.
But then on another post I was told to get a mic with phantom power, then to avoid USB.
My application is very simple freq res tests to see if the graphs supplied with drivers is accurate or not. And to get the data when they are not provided.

As far as I'm aware, the ECM-AC2 doesn't come with a calibration file. I actually happen to have a ECM-AC2 on hand, and I did a quick and dirty comparison with it and one of my professionally calibrated mics and found it surprisingly close below 1.5kHz (like, less than 1dB). Above 1.5kHz it's not as close, but I'm expecting that to be my quick and dirty fixturing and I think it's worth trying again with some better fixturing.
That being said, if you want an actual calibrated mic, the iMM-6 supposedly comes with a calibration file. I can't speak to how correct that file is, I've heard stories of other inexpensive factory calibrated mics being off by several dB.
