Today I go through what I'm using currently for podcast production.   Here is the list:

Mackie 1202VLZ4 Mixer Behringer Composter PRO XL 2 channel Compressor, Limiter, Gate Denon DN-300R Rack Mount Digital Recorder Heil PL-2T Boom Heil Shock Mount (normally for a PR40 Mic) Electrovoice RE-20 Mic  and/or Audio-techincia BPHS1 Headset Mic Zoom H5 Handi Recorder Behringer XM8500 Hand-held Mics for extras or portable

Do you need all this stuff?    NO!   This is just what I use currently.
