Yes, I know, I want one too. But I tell you what: I want one with a hand guard. Otherwise every lightsaber battle would consist of sabers clashing and then their owners sliding as quickly as possible down the shaft to lop off their opponent's fingers. You say: Lightsabers can slice through anything but another lightsaber, so what are you going to make a hand guard out of? I say: Dude, if you have the technology to make a lightsaber, you have the technology to make a light hand guard.
They stand out like a sore thumb in every environment but snow, the helmets restrict view ("I can't see a thing in this helmet!" -- Luke Skywalker), and the armor is penetrable by single shots from blasters. Add it all up and you have to wonder why stormtroopers don't just walk around naked, save for blinders and flip-flops.
Star Trek fans, don't get smug: I'm going after it next."
