Some of my favorite light saber websites
http://kitsabers.blogspot.comBlack Tactical's resident sabersmith. Kit builds customs as well as standard issues. All his creations can be found at Black Tactical's showroom
www.ultrasabers.com Manufacturers of Mass Market sabers, low cost, but very simple in design. Metal hilt sabers are virtually indestructible, I personally have several.
http://www.parksabers.com/The Most Powerful Sabers in the Known Universe!! Highly detailed, durable enough for full contact dueling and containing technology other saber smiths can only dream about, The only problem with Park Sabers must be the high cost of owning one!!
http://www.saberforge.com/Saberforge's products are targeted at duelers who want a show worthy saber they can hammer away with. All sabers are machined from T6 aircraft grade aluminium and come with heavy grade battle blades.
http://www.thecustomsabershop.com/TCSS sells Modular hilts, where each hilt is composed of metal sections screwed together to achieve a highly personalized saber. Prices depend on the components used. Not for the Padawan!!
http://ledsupply.com/Not a saber smith, but a supplier of LEDs and all associated electronics
