I saw a Black Series, Force FX Lightsaber on sale from Hasbro. It has a blue blade, but I’m not sure whether it is from IV or V. I say this because I currently have no unedited copies, and I can’t figure out which lightsaber I’m looking at when I watch my 97 tapes or my Blu-Rays. The lightsaber runs about $150, but depending on where and when you get it, the price may change. Also, there are many reviews that the lightsaber is not very loud, so don’t be surprised when you get it.
