Comparisons of Non-Linear Video Editing Packages?

kickabear asks: "I'm working on an independent (that means I'm poor) film. I'm looking for a site (or a book, I'm not picky) which reviews various non-linear video editing packages. I've found a few sites but I can't really find anything that does a side-by-side comparison of the features and capabilities of products such as Premiere Pro or Avid Xpress Pro or the 20 projects listed on Sourceforge. The project will be filmed using a brand new Sony HVRZ1U HDV camera, so if any comparison sites lean toward HDV/HDTV, that would be favorable. Any information, war stories, or advice would be appreciated."
