Mine:

• A couple of very cheap sectioned trays. Shallow enough to make grabbing tokens easy and enough sections to organize them. We use these for pretty much every game with tokens.
• A side-table to help deal with table hogs.
• A couple of those foldable dice trays. I don't actually use them for dice but as a flexible funnel when bagging things.
• Notepad, pencils, eraser
• An empty tea tin. I use this for some games where you frequently draw items from a bag because it's a lot faster.
