Ok, my 2 cents for what it's worth;
bought the vader, Clone Trooper, Maul and Obiwan.
These figures are NOT worth their price, but that's only strictly speaking. Like someone mentioned they should be only half as expensive. Then again as fair as I know it's the only decent solution for someone who isn't willing to spend GG prices or worse. I personally find GG stuff deliver better goods for our money.
Obiwan is a bad figure imo. Vader was ok but a character like this deserved better in my collection so I sold him and will get the SS one. Clone Trooper is fine, not a lot of detail but since I'm not crazy about the prequels it'll do. Darth Maul is pretty damn awesome though, great pose, very good likeness.
I've heard that these figures are getting better and better, so I'm taking my chances with the Tree Yoda, Sandtrooper, and Scout Trooper, might get a Boba as well.
Give them a try but don't expect a lot more than a blown up action figure.
