Meh. When I was a kid, none of my friends or I had plastic lightsabers, primarily because they didn't exist at the time. So we improvised. Sticks, broom handles, yardsticks and umbrellas all got pressed into saber service. At least I always had the best mouth-made sound effects, no matter what I was fighting with.

I usually kicked ass at it, because so many folks thought the point of swordfighting was to smack the other guy's saber with yours. That mindset leaves you ill-prepared to defend against a swipe at the legs...
