I Am Second is a tremendous site which offers video-based testimonies of people whose lives have been changed by Christ. Many of the videos also have Bible-study discussion guide that goes along with them. I have found these are excellent (and free!). I have used the videos in sermons, and I have even done Bible-study series utilizing these videos. They are short (3-6 minutes) and well done. Some of the individuals are well known (such as Tony Dungy).
