Note that studio mics recommended in this thread, like the SM57 or the C1, need to be plugged with an XLR cable into an audio interface. Focusrite, for one, makes good USB audio interfaces - but it's still an extra device to buy and then keep on your desk/carry around (and, optionally, to understand).

For conferencing, it's much more convenient to just use a USB mic. I can recommend the RØDE NT-USB for this purpose - all it needs is an available USB-A port.
