I could have also entitled this thread "Imperial 4-pack renews Lando's hope in SW collecting". I feel like this is the first SW figure I've gotten since....oh, before you were born...
I found a few of these last night at TRU in Times Square, NY. I bought 2, despite their pricetag (possibly the only thing I didn't like about the set). I'm psyched with this 4-pack. Despite the fact that Vader isn't an army builder, he is the best Vader we have so far...and when I swap heads with the upcoming removeable helmet Vader, and give him softgoods cape and robes, he'll be the ultimate Vader...
The stormtrooper, who many of you know has knee articulation, can be posed perfectly with the E-WEB tripod cannon. I can't believe this wasn't brought up in any of the reviews on the collecting sites. He looks great. If you have more than one of the stormie, you can pose the other futzing around with the power supply. The E-WEB is a two man operation, apparently. Either that or the Stormtroopers have a pretty good union.
I didn't need another Interrogation droid or mouse droid, but hey, they look good in the background. And if the Empire ever needs to run interrogations en masse, I'll be set.
Couldn't be happier with the R4 unit...now I won't have to paint my own!
Despite the compaints I've heard about the quality of the plastic on the AT-ST driver, I'm very pleased with these as well. I don't have a problem with the plastic on this, as he'll just be window dressing when he's not completely obscured inside the AT-ST. Plus, if you think he looks bad, perhaps you should take a look at this...

I know, I know....that was cruel.
Lastly, it was a great idea on Hasbro's part to throw us a bone and give us some stands for once! Bravo Hasbro, bravo...
