You will love the Sideshow Han. It's going to be huge! Vader will be very impressive.
You should pick up Luke now. The flood of them is on ebay and dealers are trying to get rid of their extra stock. It is easily worth the $250 retail price and you can find it for $150 or so shipped now. Go for it!
I cannot stand it when people have nice collections but they are just placed right by each other, giving it a "junky" feel.
