I'd say $400 tops. I value the side boxes at $100 a piece, that is what I paid for the full set drawer version. The main box is a rare version so if you are really set on that layout compared to the normal 7 drawer version, maybe, but I'd still say $200ish for it. I generally don't value 26" wide boxes very high since they are just that, small boxes. Also there is a ton out there so you miss one, another will come along.
