Deadeye Elite Prototype Headgear from The Mandalorian Terror [heroic 4] on Balmora republic side. I think it is a smuggler reward only. I think I saw one similar on gnc before, maybe not exact color scheme. Edited May 2, 2012 by nogell

Dam I was hoping that would be on the imperial side, ok thanks.

Anyone know where I can find the rest?

Foremost advice for finding most things is to look at their item level, see what planet lists that level as part of its level range, and go do all the Heroics. It's not an easy answer, but it usually helps. If that fails, look for item boxes of that level, or kill a bunch of silver- or gold-star mobs around that level. Item boxes might be mission rewards (another reason to check the Heroics of planets of the appropriate level range), Crew Skill results (primarily Treasure Hunting, but I think Slicing does it sometimes too), and some can be found on the Commendation vendors. The box's item level is listed in its description, and it will give items of exactly that item level.
