I would go with Pelican 1504 with m4/3 gear... for utmost down-and-dirty ruggedness (which I seldom actually need).
So I decided to go with a Pelican 1505 padded divider set (same set that comes in a 1504). I like the versatility of being able to customize the dividers whenever desired.
which will fit in a Sterilite plastic latch box while at home/RV.
And when I want to travel with most of the gear, the padded divider set drops into a Halliburton aluminum case. (I add the convoluted foam lid liner to cushion the top of the gear before closing the case.)
However, a great, low-cost way to do this, of course, is to go with a Pelican, like the 1504, which is in the $135 range, or so, from B&H.
The padded divider set is easily removed from the Pelican and placed into a Sterilite Latch Box for in-home storage of the gear, a Halliburton for lightweight light-duty travel, or the Pelican 1500 case for "throw-it-around" ruggedness.
