If the jet pack is the equivalent of the ability to fly, that would be in the 150 shard category. Since it only gives a boost and softens the fall, it can cost 100, yes!

Since the drones are both a shield and a glider on top of making holograms, they would go in the 150 shard category since they have multiple capabilities. I would assume they come as a set, so a few can be claimed at the same price (just make it a reasonable amount).
