The most popular like you said are Combustion and After Effects. Maybe there's a plugin for Combustion but I don't know. For more info on the AFX/Maya import feature, you could check these how-to's out:

or watch a Quicktime movie of it in action on adobe's site:

You should give AFX another try though...the learning curve is steep but it's like Maya, once you learn the tools you can create and create.
