For those that don't know, I'm a professional, but go ahead and try this at home also! 
I'm now the service manager at Star Rentals in town. I needed a box that handled some weight and volume. I am being a cheapo and refused to buy another name brand box. I've had a Matco double bank early on in my career. I have a Snap-on top box that rode in the truck for four years as a road box(amazing durability)! I have two Blue-point carts currently. So I did tons of spec comparison shopping for the last couple months. Snap-on will always be my favorite for top of line choice, I just didn't want to spend the money. So to set my limit at $2500 just might have shot myself in the foot. I went with this, both top and bottom.

So far, I'm really impressed. The 44" pro is no better than a homeowner setup. This one, guessing the 72" is similar to the 56", is pretty sturdy. Drawer ratings are solid with 200lbs for the large bottoms. Welded together not bolted. Almost 3500lb gvwr. Top box has 1600lb gvwr. I have about 190-200lbs in the bottom left drawer and it still slides decent. All of my 3/4" & 1" sockets, ratchets and impact are one drawer up(heavy). This box is only going to sit against the wall and not roll around hardly ever. If it was to be a roller I don't think the drawer locks would hold up. They are just plastic tabs on one side not both. If it's to be rolled around, I'll be locking with the key to be sure, especially the top. I'll be adding two lockers to it in the future. That will free up multiple drawers by getting big wrenches and other hanging tools out. I have a couple of air tool hanging brackets to go in the lockers also.
As I get back in the swing of shop life, I'll update this post.
