A detolf should work, you got 13" from back to front, but they are better for scales or hot toys, but that's would be a means to an end rather then a good shelf. You wouldn't get any use other then a place for Guts and Femto, and then one of them would have to be on the bottom... Unless you raise a detolf (like omlet did) the bottom shelf is all but useless for viewing.
I went for the REGISSÖR, costs more, but it's nearly as deep as a BESTA, comes with feet, and with glass doors. Was easy to put together, with a max weight of around 30 pounds per shelf, all the Shelves are adjustable except for the wooden middle shelf..

I plan on having Queen of the Dead, Keir, Guts, and Femto in it, but since 3 of those are a way off, I've done this with it for now:
So the bottom half of the unit you don't use for Guts an Femto could be used for whatever...
