I don't really like the Silver pewter Vader. It looks a bit strange. But I think everything it's about fashion and repaints...
I too have a great deal with an online shop: Toy Palace. Marco Russe has great offers for me and I won't pass. I already have on pre-order the Droids set and Leia.
At home I already got: ROTS Vader, Scout Trooper, Sandtrooper and Snowtrooper. This week I'm expecting the Koto Stormie to arrive as well. I only collect OT imperials and Droids, I'm passing the Jedi and even clones, since I'm not a big fan of PT. Leia is an exception.
BTW here is my
Kotobukiya collection, or check out my signature or you can find it
