ArtBin 6980AB Super Satchel Deluxes stack well and have a nice handle for carrying, and are relatively cheap ($26 on Amazon). They have a undivided top section for maps, rules, etc. and plenty of room for minis. I have two of them containing the 1st and 2nd Edition plus all 2E expansions:
Miniature storage plus card decks in the back:
Opened top for rules and map tiles:
Popout side trays for tokens, dice, minis, etc.:
I hope this helps! I use a few of these for Mansions of Madness (I discovered this item in the BGG Forum for MoM) and Super Dungeon Explorer too.
