New Poll: What lesson material do you use?

While I have been working on my upcoming Sunday School lessons, I started to wonder how you guys put your lessons together. Or better, what do you use for the material in your lessons? So that is the weekly question.

What lesson material do you use:

1. I write my own
2. We have a team that writes it
3. I use curriculum, exactly as it is written
4. I use curriculum, but I modify it to fit the class

Leave a comment and tell us the pros and cons to using a certain method. Have you used more than one and found one worked better for you? Does one method work better at certain times? Does it make a difference whether you are the one teaching or not?
