I got one of those deckboxes for Christmas, and so far it's been fantastic.  They're the same size as the Dragon Shield boxes, so it accommodates a double sleeved EDH deck worth of cards.  In my case it fits a double sleeved Vintage deck + sideboard + another sideboard worth of cards I swap in if I want to play Legacy.  Also I believe Leifkicker takes commissions for custom boxes, but I would expect that option to be quite pricey.
I also have a box from these fellows:
