I don’t usually just post links of stuff to purchase, but here are a few things on massive sale right now that would be good for a podcaster/videographer.
This digital audio is on massive sale, and it a really good one.
This is the one I use, the Tascam DR40. It is a fantastic device, as you will see if you look at my podcasting links. Also on HUGE sale at Amazon.
Finally, this is the USB Microphone I use. It is the “old” model, and thus on bigtime sale, but the newer version just has a headphone jack. Other than that, the old one is the same. Great sound for this microphone. Plugs into the computer. Simple.
