Wow - some nice looking ones in there. Not quite enough to buy a case, but lots of singles.
After the first MM set, which I bought only a few singles, this one looks much better.
As a 3.x player, not all of them are useful, but that Psychic Sentinel can certainly be used as a ruby golem.
Let's see....
1. Adult brown dragon - cool
3. Aurak Draconian - Good
4. Balor - nice
5. Barghest - servicable
6. Huge beholder - excellent
12 & 13 - Duergars - servicable
15. Huge Green Dragon - very nice
16. Elder Iron Dragon - Usable
24. Goristro - I'll take 4
30. Psychic Sentinel (this will be a ruby golem for me)
31. Remorhaz - about time
33. Salamander (2 please)
34. Scarecrow (kind of an ugly mini, but servicable)
35. Sivak Draconian - nice to have
38. Talon Slaad (as a Blue Slaad)
40. Yochlol (finally! I'll take 4!)
No use: Air Archon Zephyrhaunt, priestess of bane, chillfire destroyer (any ideas how to use this, 3.5 fans?), chull (already have that), djinn (already have a djinn), doom dreamer (boring), earth archon, foulspawns, frost titan, githzerai (plenty from earlier sets), goblin (plenty from earlier sets), hezrou (the hezrou from a previous set is my all-time favorite mini, so no use for this one), swarm, human, irontooth, minotaur, griffon, slaad spawn (no use for 3.x), war troll (have enough trolls).
So I have use for 17 of 40.
