...it seems to me that putting a price on these crystals just causes meta-game problems, especially if starting at "Knight" level play. 10K is pretty arbitrary anyway, especially considering that these items are usually considered "priceless" and are usually the focus of quests or other great effort.
Besides, you could walk into a ship dealer and you'd need 10 or more just to buy a YT-1300 ... which seems kind of cheesy considering what a personal item it is. No price at all would be better.
