For our training videos, we use the Blue Microphones Snowball. Blue Microphones | Snowball - The World's First Professional USB Mic
And our Mac users use Camtasia. Camtasia 2 on the Mac App Store
The microphone is really great high quality and Camtasia is really good for letting you edit on the fly as needed.
Thanks, Mike. We have already placed an order for equipment, and I will let this group know how those items work out!
