My excuse on getting a Greedo was a little lame, but it wrked for me...
I figure there's umpteen Rodians in ANH. There's at least one other in the Cantina that looks like Greedo and Jabba had a whole little squad of them at the Falcon, so I've just bumped the older Greedo's back as generic "Jabba Goon" or Cantina Patron Fodder.
Like I said, it was an excuse to me... Helps me visualize them as unique characters instead of Greedo upon Greedo.
I myself have seen one Stormtrooper, and nabbed him because the card's so spiffy. Saw a TIE Pilot too and skipped him, and now wish I hadn't.
I saw the Bespin Wave all of one time, and boy am I glad I bought 2 CCP's when I did... I debated doing so because it was the only two they had, but I went ahead and was a little greedy that day... I figured they'd probably ship again soon as I'd heard other areas had Bespin Wave in abundance. Then nothing ever resurfaced of that wave. Very strange.
Dagobah's all over though, and select from it are starting to earn pegwarmer status I believe.
All the while VOTC remains a weird case... 1st wave has remnants that hang around, but there's many (I'd say most) stores in my area that have completely empty VOTC pegs. The few that do have VOTC are usually TRU's or KM's, and they have Han's and Ben's with a straggler Leia every once in a while. There's no "abundance" of these figures that I've heard other areas have, they're just scattered here and there.
I hope this means ESB is going to be similarly easy to find for me at some point, and that ROTJ is REAL easy to get then (cross my fingers on that, but I doubt it happens).
