Could anyone recommend a good tackle/storage box that has enough space for Descent plus all expansions ? Thank you very much !

Not a one stop solution but these guys could help you out. I am interested in ordering from these guys but I am not sure what I would order yet.

I got a four layer toolbox, where you can take off the layers individually. It is about 1 meter high and has room for the game, and painting supplies. And get either a lot of small bags with zip locks, or small boxes for it.

I've found some great storage options at the container store. I'll check them when I get home to see if they have a name or product number.
