Buying used snap-on box Vrs new bigger china box

I'm diesel mechanic at a Mack truck dealer. My craftsman chest is over flowing, I cannot lock it anymore and I have two tool bags full. It's definetly time for a new tool box. Snap on guy has a older Krl1000 . He wants 2k for it. But I am also looking at Menards workforce and if it wasn't for the American made part I would care less.

Much bigger and I would have room to grow. Quality is nice also.
But it's made in china. Thoughts? Anyone have a workforce tool box or a American made tool box for sale? :)
I would stick with the name brand boxes,Snap On,Mac,Cornwell or Matco.
The are built for everyday use.The drawer height and spacing is less wasteful.Some even warranty the slides for life.
I have had several name brand boxes and never had problems,I down sized and tired a box from Lowes and that one wanted to turn over if more than one drawer was opened...I got a lot of tools.
I tried one of the stainless steel box combo and one of the caster bend in with the weight of my tools.
The Snap on box you listed is 29" deep and the menard and other cheapy box are 20" deep and are not very stable.
When I sold my Macimizer Super Station in 2001, I bought an office cabinet to hold all my blister packed tools(compression gauge,ball joint press,fuel injector tester,coolant pressure tester,fluke,dial indicators....)from an used office supply place for 75.00 to free up my smaller box....Just a thought.
I would go for the Snap On box and pass on the China ones.
Here a similar picture of what type a cabinet I was talking about.A file cabinet would work too...They lock too.
I got my office storage cabinet full and also you shelves to store the rest of diagnostic tools but I know you are in an environment where you need to lock them up.
