I have the master replicas ANH vader force FX saber & it does indeed extend out & return into the handle. (the light does, not the actual tube) plus it is almost identical to the screen version (save for the speaker holes in the bottom, but even those are molded to blend in so they're hardly noticable). It is absolutely incredible! easily the closest thing to a real saber. & i got it at a retail outlet (Borders bookstore) for $99. Much better than $160.... Oh, & incase you didn't know, the sabers on that site ARE the Master Replicas ones. MR has made quite a few different versions, but each one has only been produced for a brief period. The Luke ROTJ saber is one of the hardest to find. & from what i understand, the ANH Vader saber has been discontinued, but they now offer the ESB Vader saber & will soon offer a ROTS Vader saber.
