Agree with you that angle-poise is essential. The flexible neck type are difficult to use, and have a tendency to topple over because of the small base.
The Craftlamps look very nice, but are a bit expensive.
Other considerations include:
The good ones will have a small lens of higher magnification ground into the main lens, which can be useful (I use mine to dig splinters out of my fingers
) .
Some come with a shelf mount only, others come with shelf mount and an interchangeable base plate, or alternative mountings, like the one C-3PO has. This give you more options and is an important consideration.
