Great review Michael!
I received my Medicom Vader... and I'm fairly happy with him. The fact that his helmet keeps falling off is a bit irritating. With shipping I paid $195... a bit high on the scale of what you stated in your review is the going rate (although I would REALLY like to see the retailer that charge only $150 for him!)
Anyway, I just received a e-mail from the guy I bought the Vader from saying that he is taking orders for the next figure, the Stormtrooper that arrives in November. With shipping, he is offering $197.88 for him. I only have to put $50 bucks down now to order him.
I'm still on the fence... should I order him or wait for a peek at Sideshow's offerings? Besides, how long do you like it will take Sideshow to get around to making a stormtrooper, anyway?
