For a newbie, I like the least expensive version of Sony Vegas. A lot of the inexpensive editing programs are dumbed down, for non-filmmakers (more for home-video kind of stuff). So, they're easier to learn, but you're really restricted in what you can do with it. Sony Vegas, however, has an inexpensive version that functions basically the same as even the most expensive professional software out there. It doesn't have as many features, obviously, but the basic editing workflow is the same. It'll take longer to learn in the beginning, but it'll pay off in the long run. Plus, it has a free fully-functional 30-day trial. Can't beat that.
