Found the Battle Droid w/ background last night at TRU in Vernon Hills. Think I snagged the last one, but I stoped looking after I found it. That was the last one, so I have all 16 figures with the background. Pretty cool, I don't forsee them being worth anything, but I think they look pretty cool. The ones with the purple background really make the figure stand out.
No TIE or Snowspeeder at my WM, but I'll check today!
