Where to Get Jobe Clusters QL 100+?

There seem to be Jobe Clusters in the ICC implant shop up to QL 100 and also in the shops in Jobe.

Is rolling missions and random loot the only source for Jobe Clusters over QL 100?

There are terminals with QL 200 and QL 300 jobe clusters in the same implant shops :blush:
