I ended up buying the sams club offering for $28 shipped and couldn't be happier. It doesn't feel cheap at all and is rated at IP55.
Unfortunately, word got out on this Sam's Club case. It looks like a bunch of people saw an opportunity to make easy money and cleaned them out the end of January. They are selling them for between $40 and $60 on Amazon and eBay now. Sam's Club just says out of stock and I haven't been able to get an answer as to if Sam's will ever stock it again. Quite the bummer.
Member's Mark 16" Safety Protective Box - Sam's Club
It currently holds the mavic, controller with guards, power cables, 3 batteries (one on mavic), charging hub, SD cards and reader, four extra props, lightning cable and microfiber cloths. Theres also room to make another slot for a battery (or larger) when needed.
This will be my 'home storage' case for the mavic or used when I need protection on a road trip or something like that. I have a small lowepro camera bag for when I need easy portability.
Fantastic for the price.
