I have several of that style and size shop cart. The first one I bought was a Craigslist SnapOn. I needed an extra shelf and the SnapOn dealer told me to buy a shelf at a local tool store and save $100. He told me that there is a bunch of these tool identical shop carts, all made in China, on the market. I bought a second Craigslist shop cart, this one with three drawers. It had MAC livery and one shelf. I added a SnapOn folding side shelf to one of the carts then put the folding shelf in storage. Right now, the Original SnapOn shop cart has a MAC side cabinet on one end.
All of these carts have **** casters as OEM. I did change the casters to Made in Germany BLICKLE casters. The four Blickle casters cost more than a no-name shop cart.
Everything interchanges between these carts. The bonus is, you can buy a low priced HF shop or SUNNEX cart and upgrade it to any label you add. I picked up one of these carts from a "thirsty" friend for $20. I put a SnapOn badge on it and sold it in two days for $100.
