Here's my cart at work. All company tools, I had to gather up all of the tools when I started a year and a half ago because they were strewn around the shop. They didn't own a ratchet or a full socket set. I only had the cart with an old snap-on little top box that I brought in. Found this box on clearance one day while perusing Home Depot with a buddy and bought it, boss reimbursed me. Next thing is talking him into a 60"x24" Durham cart so I can have a mobile workbench with a vise. I've just made do with what was available to this point. I'm afraid that cart is going to collapse some days when I've got it loaded with tools, supplies, cords, etc. from a job.
Also have an HF 44 to store another full set and the less commonly used tools.
