Using a Kennedy machinists tool chest is not a bad idea. I have one that is under-utilized. Also a similar craftsman box that is also just collecting junk. I do 99% of my wrenching in the basement nowadays, so a portable is less than fully useful.
If you really want to go down a rabbit hole of portable toolboxes, the toolboxwars hashtag on instagram is good to waste a lot of time. It also got me to waste $14 so far. They usually modify Pelican cases, which is expensive, but not as expensive as the Park or other pre-made boxes.
