I'll take photos when I have a second, but I found small plastic containers with twelve imp-width bins, six on each side, with individual lids, and my collection has grown to span across three and a half of these. I organize alphabetically (and ignore 'The' if it starts the name). Letters I have a lot of get more than one bin.

For full bottles, I have some other small plastic containers, who's divides fit bottles fairly nicely. Those I don't really organize, because I don't have as many. Nothing goes into the plastic bins until it's been added to my ScentBase, because that is the only way I can remember what I have.
