Not many actually. In OT, passed on Vader (too many issues and need for mods to me, still prefer the Hurricane/Kaiyodo sculpt, but will likely grab the next HT Vader where the kinks will be ironed out) and Luke Stormtrooper (only because I have farmboy Luke and the stormie.)
Did buy two Chewies and two stormies. Still mulling the sandie (looks better than stormie) and will probably grab it, but I have the Marmit and it's pretty close to as nice as the HT. Didn't buy the full Ben, got parts because I didn't like the inner bathrobe. Resold my Han to a buddy because I thought in-hand it would be better than pics and wasn't to me (even though I got it fairly cheap, I should have hung onto it as an investment
) and know there'll be a HT Han Bespin shown by middle of this year, which I'd prefer.
Have Leia on PO and really like the look of that.
Haven't been blown away by any of the HT figs so far except Chewy (which yes, has its issues too) and the most recent, farmboy Luke, I was "lukewarm" on.
Even the HT stormie helmet looked to me more Don Post than ANH stunt as it should have. I was expecting HT to totally nail each SW likeness and on that basis, I've been somewhat disappointed over and over, even though we've certainly gotten some gorgeously hyper-realistic heads/helmets and some incredibly well done outfits/weapons.
