If sticking with DCUC-style figures, there's some issues that we all must face. . .

Catwoman -- DCSH all black, Gotham City 5 purple, or Arkham City 2pack? (I vote all black)
Robin -- wave 16 Grayson, wave 3 all red, or Dynamic Duo 2pack (my fave is the Dynamic Duo 2pack version)

Joker -- wave 10, Batman Legacy, or Mad Love 2pack? (I like them all. . .but vote wave 10)

Riddler -- wave 5 or wave 16?

Croc -- DCSH or the older 2003ish one? I actually like the older one, and it's cheaper.

Two-Face -- Gotham City 5 or DCSH?

Lots of choices, and some of those will really eat into that $600 budget.

Look at KenM's pictures -- that's a pretty definitive collection there.

I know others will disagree, but I'd also add the DC Direct Commissioner Gordon, Huntress, Alfred, Hush, and Ra's from the Hush series. Or maybe the Ra's from DC Direct Trinity instead. Unless you want to hold out hopes that Mattel will cover these versions of the characters.

And then there's the DC Direct Birds of Prey Oracle. . .
