Free option: The built-in microphone on your computer.
I don’t recommend this option since the audio quality will be lower than podcast listeners are used to hearing, and this will definitely detract from the number of repeat listeners you have.
Low cost option: Logitech ClearChat USB Headset, $29.99
This headset will plug right into your computer’s USB port and will give you a decent quality, hands-free microphone.
Medium cost option: Audio-Technica ATR2100-USB Cardioid Dynamic USB/XLR Microphone, $79.00
This microphone also plugs into your USB port, but it is not a headset. Instead, this option offers a freestanding microphone.
High cost option: Heil PR-40, $350.00.
You cannot beat the audio quality this microphone provides. It is important to note this is not connected via your computer’s USB port. You will have to take the additional step and purchase a mixer if you go this route.
This software allows your voice to be recorded, edited, and converted into an MP3.
For Mac: GarageBand.

Zencastr. This is what I personally use to record every episode of The Business with Impact Podcast.
For both Mac and PC: Adobe Audition.
Skype For Mac: ECamm Call recorder. Automatically record and save call audio and video on your Mac.
For PC: Vodburner. Record your Skype video calls.
A mixer is an electronic device for combining, routing, and changing the level, timbre and/or dynamics of audio signals. This piece of equipment is OPTIONAL
If you are going to go with a Heil PR-40 microphone and need the XLR connection, a mixer is important.
Mixers are not cheap, and I wouldn’t recommend using one until you know your podcast is PROFITABLE.
