The Lowes box is a nice one for the price. I have an old MAC Economizer John Force Edition and a tool cart to keep my sockets on. I've been looking at the Lowes box as an inexpensive upgrade to get more room.
I've been in shops with guys who are engaged in the toolbox races. To me, most of 'em are compensating for something...:D And most of the guys I've worked with who have those big, bad, expensive boxes have very little tools to show for it because the payment on the box itself leaves 'em buying cheap or no tools.
My box has never made me money. The tools inside have.
Comparatively, the price on the box you just bought is a good price.
