The best 3 D&D minis are...

[Varianor Abroad]

1. Bulette
2. Aspect of Orcus
3. Beholder*

*Because I actually own one. There's a case to be made that the Red Dragon is a fine miniature to have. Oh wait, got one of those.

 

[KenM]

No love for the human commoner?

 

[Kyuss Knight]

I think that I would have to take:

Beholder
Medium Black Dragon
Balor

 

[blargney the second]

I just remembered the Ogre Mage - that one is a really nice figure.

 

[Thunderfoot]

Behir
Beholder
Otyugh

Of course, this all depends on the upcoming set - I have this strange feeling this list would change dramatically AFTER their release.
