Cliegg Lars for the Prequel figure. He would be a very nice figure with his chair and all.
Next, choose your most-wanted Sequel action figure:
Hem Dazon, Arcona from Cantina
General Tagge, Death Star Conference Table
Black Bespin Security Guard, remake of vintage Cloud City figure
Han Solo screaming in Bespin Torture Chair, as a basic figure
General Veers, from AT-AT with removeable Hoth Battle Gear
Yarna dal Gargon, Jabba's Palace fat dancing girl
I'm gonna have to go with Yarna because an Imperial officer over an alien figure is no good, and the Han and Bespin dude would be cool but not as saught after as the Yarna or Hem.
