Has anyone tried out money4banners?

I have not encountered money4banners and have not heard about it anywhere else but on this discussion. It's too bad that there aren't any other member who can contribute more so that we'd both know more about the program. I'm concerned of what the banners would look like and how much they actually pay. I don't want to ruin my site layout just to accommodate a banner that would actually ruin my readership because it will be showing unrelated content. Thanks for the response on my discussion :)
