Can anyone recommend a module that provides the capability of "easily" creating blocks that combine different sources of content?

For example, creating a block that has two sections to it. One section would contain the latest blog posts and the other section would contain the latest news article postings.

I've tried a few different modules that I thought may give me that capability, but they either are very limited, don't work, or have no documentation regarding how to operate it.

I realize that there are methods for manually creating or hacking a block to produce this kind of functionality, but I'm looking for something without too much complexity, and that doesn't require too much PHP knowledge.
