Seriously -- I would buy just about one of everything that Levenger sells. Their tage line is "Tools for Serious Readers." In addition to book lights, bookstands and book shelves, they carry a variety of office supplies, bags and totes, lighting, even furniture.
The new Bloomsbury Bag is a great deal. At $58, it's a great bag for toting around all your books -- plus it's stocked with a bunch of extra tools like a book magnifier and Levenger note pad. (You have to try their notepaper sometime. You'll hate going back to the cheap stuff you get at your local office supply store.)
Now it's just a matter of restraining myself from buying it.
