I get inspiration from Adam Lisagor, his videos are online at http://sandwichvideo.com/. He uses people in his product videos, not just the product. They have a very personal feel, which definitely reaches me. Of course, he has more than a bootstrap budget, but if you want to try filming people, check out The Frugal Filmmaker's blog for tips on setting up lighting, etc. on the cheap http://filmflap.blogspot.com/. Good luck!
