Another option for deluxes or smaller is Obitsu's multi stand. It comes with parts to allow many display options---I like to use it to display some jetformers flying in their alt mode. Deluxe figures would probably be straining the upper limit of these stands though; mine are very wobbly when you nudge them. We'll see if they hold up over time. Still, they're cheap and good for posing.
