I couldn't get an OJ Custom Techblade for Qyzen very cheaply,so what I had to do was simply do Herioc instance missions on Coruscant over and over until I got 14 Coruscant Commedations and then I used that to buy a low level OJ Techblade from the Coruscant Commedations Vendors. :'(
Ugly looking sword, But it's working somewhat. :'(
I am currently level 38, so I got a lot of strange looks farming such low level Herioc Missions, but hey, I got an OJ techblade.
