Short of getting a Mac and using iMovie, what are the alternatives that you'll recommend to a non-profit organization that needs to produce simple (but polished) videos to showcase their community service activities to raise funds.

Currently they are using Windows Movie Maker but have sort of outgrown it. I installed Jashaka for them, and understandably, they couldn't grok it at all. Their current system is powerful enough to handle most video editing tasks.
