I think you'll have a hard time at securing one at that price, as when they do rarely change hands it tends to be for a lot more but I guess it depends what's out there.
I paid 150 000 000 sirius credits for mine from admins
i dont believe any one owning a barge want anything less
and if they became unobtainable from [Admins]
well then you have a vintage model there and that just
makes the price go double.
I might be wrong but looking at 80M for a barge might
not lure the reaction u were hoping for.
