These can be from any of the Star Wars lines in the past or present.
I think that the following will never need to be resculpted (I'll just name a few):
Grand Moff Tarkin
Hammerhead (Momaw Nadon)
Hoth Gear Leia (Maybe the best Leia that came out of POTF2, but Slave Leia was more fun )
Figrin Dan (aka Cantina Band Member)
Most of the Jabba's Palace aliens with the exception of Bib Fortuna (he'd make for a good resculpt)
What figures do you guys think are fine the way they are?
