Lots of vanquishing and power weapons. Should I setup a vendor?

[Bashar_Teg]

Hello,
I have amassed quite the collection of vanquishing and power weapons. Is there an aftermarket for these that would be worth setting up a vendor at a rented space or should I just sell them back to NPCs?

i'd pay more than an an NPC would...

I'd be buying too, vanqs especially.
