Ooh, I love threads like this! And R5Don4, I just LOVE your "boo-hoo" Medicom Vader photo. Absoultely priceless!

By the way, where exactly are the silver pieces on your IG's legs? 'Fraid I'm having trouble seeing them...
Now, as for favorites and un-favorites. I unfortunately don't own any of those excellent looking Marmit, Medicom, or Sideshow 12-inchers, mostly because they're expensive.

I mainly get 12" figures for customizing purposes, so I find that the Hasbro ones are mostly all right for what I do. So my choices for favorite and least favorite are with that in mind.
Favorites: It's hard to choose just one. I too am fond of Shaak Ti and Barriss Offee for their wonderful outfits and the super-poseable (& very customizable) G. I. Jane body -- the lack of proper feet is a small price to pay. The "girly girl" in me is partial to the Portrait Edition Amidala dolls with their sumptuous costumes -- sure, they lack articulation, but fashion dolls don't really
need articulation.

(Though when you get both in the same figure, as with the Jedi gals, that doesn't hurt!
I was pretty impressed with most of the bounty hunters, too (guess the one for whom I have a particular soft spot). Though, as people point out, Dooku was really impressive too, wonderful outfit and the G.I. Joe body... As I said, choosing one fave isn't easy.

Least favorites: Nothing new here. Zam tops the list for me, too. I had picked one up (on clearance,
of course) thinking that I could improve her at some point, mostly by trasnferring some of her accoutrements to a new body, but even that's looking like it'll be a lost cause. I wasn't super thrilled with the Saga 12" Padmé either, but I was able to improve her at least partially (
here she is -- tho' she still needs work).
