Kenk: you do not have to record a track with your face and sound in sync. You can make a video and record narration style with text on screen and have a very effective selling tool. I have a Yeti Microphone that was about $90 and USB connected. studio quality. The problem is not the microphone or gear it is the background noise. Even the higher quality videos that Laney did had background echo and back tracking sound. I have my recording set up with foam on the walls behind the microphone. Lots of guys get the egg create foam and hang it on the walls. cheap solution and very effective.
