Planar Binding: What to Summon?
 

So get this, I have an epic level wizard who has access to the planar binding spells. However I can't help but wonder what should I summon with it. What are some good ideas of what to bind with it and what to use them for because I'm not sure what I should do with it myself. All I know is I want to have something binded. Alignment is a non-issue.
