it says guild purchase is 50k, nw is this in ADDITION to having the cartel market item, or can I buy as many of these guys as I want as a guild leader for 50k ?

Someone in the gulid must unlock the Kel Dor Jedi Master decoration. They can go to their own stronghold, view their personal list of decorations, and purchase a copy for their guild. It then shows up in the guild's decoration inventory. They can actually purchase as many copies of the Jedi Master as they like, which is a real advantage in guild stronghold decorating. If one person owns a single Voss-Ka Street Lamp, for example, they could copy it six or eight times and make a whole row of them at the guild stronghold.

However, if someone buys a Kel Dor Jedi Master and donates it to the guild through the bank, the guild will have only one copy. Since the player hasn't unlocked it for themselves, they won't be able to purchase it for the guild repeatedly. In general, items should only be donated directly to the guild through the bank if it cannot be copied (purchased for the guild from personal inventory). For example, decorations obtained with Cartel Certificates or prefabs cannot be purchased for the guild and must be donated directly.

I hope that helps!
