I've been using windows movie maker and, lately, the trial of camtasia. I honestly dont think camtasia is worth 300 dollars because it doesn't do full HD. Movie maker is tough bc you have to do math if you want to insert clips into your video with sound recorded separately. The lack of ability to put video overlay is a huge weakness. I use pinnacle sometimes but the audio always seems to not line up with video even though it was recorded at the same time (something funky happens with the time)
