I got this roller cabinet probably 8 years ago, then the top cabinet maybe 3 years ago. Little more expensive than your Costco one at list price but the thing with Sears is they give pretty deep discounts on a lot of stuff when you find the right sales. I think I got 40% off each. It's got friction slides, they won't last like ball bearing and they're not as silky smooth, but they're also cheaper to buy. I don't notice any issues with mine, feels just like new yet. The minor annoyances with this box for weekend work are having to push the drawers all the way closed, and then the little silver handles occasionally sliding off. It's not a deal breaker for a weekend wrencher though, especially if the money you save will buy you a compressor or something. I'm again starting to run out of tool storage so I'll probably go to a bigger roller slide box and keep this one for specialty tools.

Some of the older Costco boxes were pretty nice but I haven't like the size and layout of any of the newer ones. Also, pick up a complete set of these socket trays:

As for the high end stuff, like Mac, Snap-on etc, they make good quality stuff but the prices are nuts. Some of their big tool boxes sell for $15,000+ without even an allen key in them. For pros it's different but it's just silly for a weekend mechanic, it's like having a big Kenworth to tow a utility trailer with an ATV in it. Which in my opinion goes for most all tools too. The vast majority of my stuff is Craftsman or Mastercraft Maximum. The wrenches and sockets loosen and tighten bolts just as well as a big name costing 2x or 3x as much. I've never had a failure with the exception of a couple 3/8" rachets that I've had 4' pipes on for leverage. Which is the wrong tool for the job and full out abuse and even then all those were replaced free of charge under the lifetime warranty. I just don't see what I could gain by having Snap-on or an equivalent.
