Searching for Bible Studies

I've just spent the last couple of hours looking at a variety of Bible study materials.... I'm looking for a few different things- Adult Education for Sunday mornings, September is quickly approaching- newsletter comes out this weekend and I should probably mention our fall programming (meaning I'd better get on the stick and plan it!) I'm also looking for material for a potential Women's Bible Study that one of the women who comes to our lunches approached me about.

Being supportive of my denomination I naturally went to the Augsburg Fortress website first, and checked out what they had available. The Book of Faith material looks decent and will probably fit the bill for Sunday AM, but didn't quite fit what I was looking for for the Women's study. So I went to look up some of the names I'd heard tossed about like Beth Moore, and Kay Arthur. I'm currently leaning towards Beth Moore's study on Esther- but this got me thinking what is it that the Augsburg Fortress stuff was lacking? Why does the "Evangelical" (for lack of a better descriptor/generalization) material and/or message play better than the Lutheran stuff (in my head at least) among the jobless/homeless population among which I find myself ministering. I'm not 100% behind everything the material claims. And there are a few things that just rub me the wrong way, but most of that is stylistic. I have a hard time trusting what they say, when they're on a big stage and have a lot of... errr... energy in their delivery; it doesn't resonate with the more subdued 'Lutheran' style I'm accustomed to. But after watching the guy who delivers the message at our Thursday who comes from a more Evangelical bent and the pastor who did it this past Tuesday from a local Lutheran church, the Evangelical message and delivery are much more enthusiastically received. Why is that??
