a better look at these sets. Head on over and check out the pics.
BB Units (1x Purple, 1x White)
BB Units (1x Red, 1x Black)
BB Units (1x Blue, 1x White)
R5 Unit (red/white R2 with swappable R5 dome)
R2 Unit (black/orange R3 with booster rockets)
R2 Unit (white/purple R2 with bar tray)
Interesting to see a little variety in the accessories for the Astromechs. Guess I'm going to try and grab 2x of the Red/White Astromech so I can display him with both domes.
