I use a Zag 4 in 1 tool box - it works great and it is very cheap, it cost me about £20 - which is $15.
It has a box at the bottom with a tray in it, if you remove the tray then you can fit 12x12 paper or albums in the bottom.
The top is a typical toolbox, and holds a paper trimmer, tons of pens and anything else you need to stash.
There's also a bit that swivels out which is good for small things like buttons, and space in the lid for flat things, like pens etc.
I don't travel to crops often, but I've found this works really well - I can take nearly everything with me.
here in the UK, where totes are very expensive, and we don't have a michaels with the lovely coupons, the Zag is king.
I think Stanley have bought Zag, as I saw some marked Stanley the other day.
