Hmmm... Can I link to Amazon here? You find the video I suggested there if you do a search for Spri pumping rubber. If the link works, you can find the video I used
here and the kit I used
here. That video is the only one I know that uses bands for weight training. If you want to use the bands for cardio training, the Billy Blanks Bootcamp tapes are great, but you might find it hard to use normal bands with them. I would suggest that you buy the Billy Bands that he uses. I tried to use normal bands, and it just didn't work :-(. Good luck, no matter what you choose!
