The Holo statues already ARE available for purchase. You just have to invest in a few packs and then use the certificates to buy them from the Contraband vendors in the Cartel Bazaar.
Is that a direct sale??????
New packs don't have certificates in, but you also have to have the rep points as well to get them from there which are from old packs, yes they do come around for sale again but most want them at level 1 not half way though the game. The contraband packs are not always available. and its more than just a few packs. Plus as said that is not a direct sale though cartel bazzar.
EDIT: to put up rep points needed for contraband.
Anyway they are at the newcomer rep which is the second tier up. to get this you would need to buy 20+ packs
