Which Eclipse for Android only?

I am starting Android development. Which of the many Eclipse downloads do I need from http://www.eclipse.org/downloads/ ?

I am only ever going to do Android dev with Eclipse ever.

Check out the SDK requirements page:

On my Mac I am using the "Eclipse IDE for Java Developers".

You either use Java developer or Jave EE, I am using the Java EE version and then follwing the guide on developer.android.com to how setting up eclipse and adt

Eclipse IDE for Java Developers should be sufficient
