One of the most famous lightsabers on the market. The Force FX lightsabers are constructed of sturdy machined aluminum and injection molded plastics. Originally constructed by Master Replicas, Hasbro has reintroduced the Force FX lightsaber line for your enjoyment! They are built as close to the original Star Wars lightsaber props as could be made while still retaining adequate space for the electronics. These FX lightsabers have sturdy polycarbonate blades with 64-LEDs running through the blade giving them the appearance of the authentic power on and off feature as seen in the movies. The lightsaber sound effects are recorded directly from the Lucas Film's archives giving these the most real lightsaber sounds and feel of any lightsaber currently on the market. All in all, the Force FX lightsabers are some of the most superb lightsaber props and collectibles to add to any collection.

Master Replicas
Limited Edition lightsabers are comprised of the Limited Edition lightsabers (LE) and Collector's Edition lightsabers (CE) by Master Replicas. These lightsaber props are exact replicas of the original Hero prop lightsabers used by the actors in the Star Wars movies. The limited edition lightsabers and collector's edition lightsabers are custom machined from high quality stainless steel, machined aluminum, and injection molded and machined plastics. Unlike the Force FX lightsabers, these collectible lightsabers do not have a blade, lights, or sounds. However, these beautifully crafted lightsabers are considered to be museum quality and come with an equally impressive mirrored lightsaber stand.
Since Master Replicas no longer manufactures these lightsabers, they can be hard to get. Your best choice is probably Ebay.
Scaled replica lightsabers
The scaled replica lightsabers are .45 scaled versions of the limited edition lightsabers. These little lightsabers are ideal for desk sized displays or budget collectors. They are made with the same standards as the limited edition lightsabers and come with scaled down display stands. They made beautiful display pieces that can be placed almost anywhere.
Ultrasabers
Ultrasabers specializes on making custom sabers. So if you want your own personal saber, look no further. Like the Force FX sabers they have detachable blades and many colors. What differs them from Force FX is that the lighting is a bit better and they are durable enough to fight with.
Most of their sabes are a bit plain for my taste though. Judge for yourself at their homepage www.ultrasabers.com.
Hyperblades
Hyperblades do not sell lightsaber per se. What they do sell is parts for other lightsabers that make them oh so much better. There are no brighter blades than hyperblades, you really have to see them for yourself. There are lots of comparison videos on Youtube such as this one.
If you want to upgrade your Force FX to a Hyperblade, head over to their webpage at http://www.hyperdynelabs.com and order your parts. Just be careful to get it right the first time as their customer service department is non-existent and trying to get hold of someone who works there is nearly impossible.
