Seriously, my Bothan Commando, HydraII, has a hell of a lot of weapons, including an E-11 Carbine Mk. II and an Imperial-issue Carbine among other things. Unfortunately, I can't find any junk dealers for some reason and I only own the demo. X_X
If you wanna find him, go to Tansarii Point Station OR Station Gamma in Ord Mantel space. Nowhere else to go, what can I say?
