Everyone start panic buying!!!
The Stockholm is interesting, but you will have to arrange around the door frames that block the middle. I have a Billy similar to the following except it has clear doors and glass shelves. I have to leave a space in the middle of each shelf otherwise you can't see what's there. The Billy is fugly, but it has served me well as my collection has constantly changed over the past 10 years or so.

I also have a Detolf. I really like the style and love the price, but find it limiting due to the small footprint, short height and fixed shelves. I'd like to see something like the Stockholm with thin metal framed door and with the height and versatility of the Billy and in black.
