I actually ended up finding them all with the help of that guide. I'd heard a lot of things about Hoth being the hardest planet to search but I got stupidly lucky and got the Hoth part on the second scan.
I want to buy the vented saber for my sith inquisitor, but the only price I see them for on the Bastion is 90 million or more. If anyone is willing to sell one for a more reasonable price, please let me know.
I have plenty of credits to buy one but never see them on the galactic market,and I thought I might offer to buy one here in hopes of someone being able to sell one,anyone have a spare they could sell?
