I had the carrying case etc wizards kit or whatever it was bakc in 2nd ed
I found the BEST hting for carrying stuff so far, to be a smallish-medium toolbox.
Lift out tray, lot sof compartments, about 2" depth in that part (the lid) ideal for dice each in own compartment, pens etc.
Lower part 4" deep, great for minis, dry erase pens, dice blocks etc.
haven't found a larger one (cheap) yet that would let me put in core books and still not be too damned big/heavy or have other problems.
Used to have metal minis in metal toolboxes with magnetic bases, but health sucks now, so stuff carrying that weight anymore, lol!
I did love the peripherals we got in 2nd ed, like trading cards (I jsut loed the art etc and got the boxes, still have them all), poster sized maps and so on
Oh and the taroka deck and dice from...Castle Forlorn?
problem I have with card minis is tha tthey are so easy broken, or lack weight/stability :/
I sitll have the Cities of Mystery 2nd card houses (damn nice), which were really great for doing city adventures. I glued like 2 pence coins inside 'em to add weight
been very useful thread I must say!!

Grabbed a Gamesworkshop fortress off Ebay too, cheap. so hope it's A-OK when arrives.
Then later on I wanna get the Seige Tower, as I want to do a Dark Sun fight, with the heroes fighting off hordes of enemies in a desert fort...Beau Geste meets Assault on Precinct 13 hehe!!
