1/18 scale lightsabers cheap on ebay
I used to check ebay power sellers etoystores (https://rover.ebay.com/rover/1/711-53200-19255-0/1?mpre=https%3A%2F%2Fwww.ebay.com%2Fsch%2Fm.html%3F_ssn%3Detoystores%26_from%3DR40%26_sacat%3D0%26_nkw%3Dlightsaber%26_sop%3D15&campid=5337377665&toolid=10001&customid=), cutesource (https://rover.ebay.com/rover/1/711-53200-19255-0/1?mpre=https%3A%2F%2Fwww.ebay.com%2Fsch%2Fm.html%3F_ssn%3Dcutesource%26LH_PrefLoc%3D%26_from%3DR40%26_trksid%3Dp2499338.m570.l1313%26_nkw%3Dstar%2Bwars%26_sacat%3D0&campid=5337377665&toolid=10001&customid=) and wiwus (https://rover.ebay.com/rover/1/711-53200-19255-0/1?mpre=https%3A%2F%2Fwww.ebay.com%2Fitm%2FLot-Lightsaber-Blue-weapon-For-3-75-Star-Wars-Clone-Trooper-Figure-boy-toy%2F353068867420%3Fhash%3Ditem52348b5f5c%3Ag%3AhTMAAOSwalde2ecH&campid=5337377665&toolid=10001&customid=) on a regular basis, but over the last months I got busy with other stuff. Meanwhile they listed more and more different sets of lightsabers and other accessories. The blue and green ones are sold as "genuine", but the red ones are nothing behind regarding quality.
They also seem to change their names on ebay on a regular basis or open dozens of different stores just to confuse you finding the best offer. So take your time and compare prices. It pays off!
So if you need to complete your action figures with lightsabers and blasters or need some acessories for your custom figures, they might have something for you!
I used a few of the red lightsabers for my latest custom figures of Darth Sion (http://www.imperialshipyards.net/SMF/index.php?topic=10186.msg221266#msg221266) and General Grievous (http://www.imperialshipyards.net/SMF/index.php?topic=10513.msg221347#msg221347).
Unfortunately, all green lightsabers have sold out quickly, but I contacted etoyshop and he told me, that he's going to relist them again. All other sets can still be found. Until then you can also refer to purpletoy2008 (https://rover.ebay.com/rover/1/711-53200-19255-0/1?mpre=https%3A%2F%2Fwww.ebay.com%2Fsch%2Fm.html%3F_ssn%3Dpurpletoy2008%26LH_PrefLoc%3D%26_from%3DR40%26_trksid%3Dp2499338.m570.l1313%26_nkw%3Dlightsaber%26_sacat%3D0&campid=5337377665&toolid=10001&customid=), but I don't have any experience with this seller and shipping is $4.99. The others offer FREE international shipping.

Beware the DC-17 blasters and red lightsabers are probably NOT AUTHENTIC!
