Not sure why people keep saying this because it's not true. The salvager will re-sell you plenty of gear that has zero achievement associated with it. Even gear that isn't useful, like the Sylvan belt from some random story quest. The salvager's purpose is to give you a way to reclaim unique gear that you may have lost. He will even sell you all of the Lucis crafting and gathering tools even if you only completed one of them (you only earn the achievement one time). Most of that gear is associated with achievements but a lot of it isn't.
