Given the various poses of these models (and the fragility of some of the thinner pieces) I decided I would try one of the magnetic storage options rather than the tradition foam trays. Hence some magnetic sheeting, some washers and a cheap tool box latter I've cobbled together some storage. So far the results are promising, but I've yet to use it long term (expect tears and frustration to follow).
As you can see, it won't fit the mat, but it will store everything else nicely. (more magnetic sheeting ordered to finish off the box)
And I do mean everything.
Now I just need to wait for some of the columns and pits from AD, and that will be portable enough to game with. Just need to paint up my factions and hope that the scene starts to grow locally.
How are other people storing their gear?
