So many good ideas at Ikea for prop displays, and of course the prices are always right as well. Every piece of furniture you see in my shots are actually from Ikea. Gotta save up money to give to MR somehow. :D
As for a Vader helmet, the rumors about a possible ROTJ reveal Vader have made me wary to jump in on one of the ROTS ones. One of those nice mid range Rubies, to go with the rest of my Rubies set might work as well. We'll just have to see.
I've really started to enjoy the idea of collecting helmets as well, but taking one look at my shocktrooper you might understand why.
