All my boxes are made by Waterloo. The factory (one of three) was in my hometown of Pocahontas, AR. The TRAXX series is a really good economical box that has decent ball-bearing slides. All 4 of my 26" boxes are this series. The only bad thing is that they are extremely TOP heavy and difficult to roll with ease even with the larger casters. My 33" box is a pro series. It's heavier built and loaded down more but still easier to roll. It's 24" deep vs. 18" plus being longer.
If I was going to start over with just one box I would buy the 40" or 42" cabinet and build up from there. I would surely get one with roller bearings.

FYI - All Waterloo boxes are import now... but what isn't?
