LOTR Diorama? Suggestions?

I was thinking about making a LOTR diorama for possible sale on ebay.  I don't know much about the figures available out there, so my question is- do most people collect the action figures that are sold at various retail stores, or are there other size figures that are more popular.  I want the scene to be sort of a standard size so people can put their own figures on it.  I was thinking about doing the Dead Marshes.  This is project #3 on my list, so I may not have it done for quite a while, but any input would be appreciated.  Thanks!
