Assuming you are actually going to set it up, NiB really should not mean anything.. These are not like your typical mass produced consumer items.
Having a distributor go through it, and make sure things are aligned and tightened as needed, and inspect it for damage and so forth is exactly what you want for your first pin.. regardless of anything else. That's my experience anyway. AFAIK many of the better distributors will do this, depending on the experience of the buyer and so forth.
