I started the Getting Simple podcast with the AT2020USBi microphone. After some time, I upgraded to the Shure SM58 and the Zoom H6 recorder, which significantly improved the quality. And then I started using the Shure SM7B (with the CL-1 CloudLifter preamp) and the Zoom Podtrak P4 recorder. I still carry the Shure SM58 when traveling as these are less bulky and more resistant.
I also have the Shure SM7B at my home studio.
