I took private lessons this past spring from a local artist, Tom Blazier.  I envied so the taboret that he had in his studio, and so I set about getting one for myself.  After looking at some of the fancy ones online ($$$) I started googling "cabinets with drawers" and the like.

Finally, I found this on Amazon and I couldn't be more pleased.  You have to assemble itself but it's totally worth it, and not difficult at all.  Solid wood.

These are nice flat drawers that have paints in some, brushes in others, and a spare palette.
