AKICO, bookshelf edition

[oyceter]

So! After half a year, my new apartment is almost (almost!) ready for shelving! I.e. I have gotten nearly all bits of other furniture in place so I can squash shelves into every remaining space.

Anyone have shelving recommendations? Stuff available in the US, especially Bay Area California preferred.

Preferences:

1. I do not like deep shelves or double stacking.
   
2. I am good with separating out trade/HC from mass markets for optimal shelving sizing.
   
3. I have a lot of manga.
   
4. I do not like shelves with doors, windows, glass panes, or anything that gets between me and my books.
   
5. I do not like shelves that waste vertical space.
   
6. I like longer horizontal spaces. I.e. I don't like really really really short shelves, a la Ikea's Expedit or those skinny DVD shelving towers.
