I know. I was just being a silly nerd. It's officially Rey's lightsabre now. But yeah, the owner of the lightsabre-that-Anakin-built depends on which period of the Star Wars trilogy you're specifically looking at. Similar to how Artoo Detoo can be Padme's/Anakin's/Capt. Antilles'/Luke's droid.
I know so was I and technically it's still luke's too! SPOILER Rey is clearly handing it back to him at the end of Ep. VII.
missed out on premium's luke lightsaber. anyone seen one at a similar or cheaper price xD?
I managed to pick up yoda and vader from deals direct for 100 each. I wouldn't hold my breath about them stocking luke but you might want to keep an eye out.
Why is there that piece on the light sabers that looks like it don't belong.
That's the transparent plastic stand. It has two configurations; you can either put the blade through the stand which can elevate the tip of the blade, or prop the lightsabre on top of the stand for a flat horizontal display.
