I wanted to add that although I think these mini-sets are really cool, I'm mildly annoyed at Lego for the way they're getting that mini-Tie Bomber vehicle out: By dividing it up into 4 parts, and including one quarter of it in each of the first 4 lego mini-sets. Simple English: you have to buy all 4 mini sets, to make a complete Tie Bomber.
Certainly a clever marketing strategy on Lego's part, but it bothers me since I only collect the Original Trilogy stuff when it comes to Legos - no Prequel Legos. Well, obviously that little selective shopping method of mine is now out the window, since I've got to pick up two Prequel mini sets here in order to get my complete OT Tie Bomber. Bummer. Oh well, at least they're only $4 a pop, so it doesn't put me out too much more. And like I said, these are really cool little sets - even the Prequel ones, and especially the Tie Bomber!
On a side note, if you're looking into picking this line up, take note that the Vader's Tie/X-Wing mini set seems to be the hot one and is already becoming HTF in my area, so snag that one if you have the chance. The other 3 sets are sitting on the shelves at several of my local Targets, so no apparent worries with those...
