I'm ready to finally buy a tool cart/ rolling cabinet / toolbox. Tools all over the garage floor really doesn't work. I want ball bearing full extension drawers. I want made in USA or similar. I've pretty much narrowed it down to these but am really looking at Waterloo the most. I don't really care which color. Waterloo TRX4112BU This one seems to have interchangeable drawers while the 4110 does not? This one has (1) full width drawer (2' breaker bar, 1/2" torque wrench, etc.). Waterloo TRX4110BU I'm leaning toward this one more due to the (2) full width drawers. I get a 10% discount at Grainger. I have a local Grainger store as well, so I think that shipping to the store would be free as it always has been for small items. I do like the deep storage area that both of these have. Drawer load rating for both is 75#. I assume these are mfg in IA but I don't know yet. Both of these Waterloo models are pretty much the same price. They have a 7-year warranty. Craftsman Professional 65566 This has a lifetime warranty. It was $1039.20 a couple days ago so it will probably be on sale again before too long. It doesn't include drawer liners like the Waterloo but those are probably fairly inexpensive. This one from Sears has a powdercoat finish as well. The casters are beefier at 6x2 & overall load rating is 2400# but I don't know drawer load rating yet. I also don't know yet where it is made but I imagine Waterlook mfg them, hopefully in IA. Snap-On KRA2106A I can get this for $1036.75 (discounted) plus tax & shipping. It is made in Canada. Drawer load rating is 100#. Mac Tools MB4220B This one is $1100 plus tax & shipping. Mac's website sucks. Kennedy is too expensive. Matco is too expensive (same as Snap-On but I can't get a good discount). Which would you recommend & why?
