Light box advice?

[cahn]

I feel like I seem to remember one or more of you has a light box (the kind that you get to stave off seasonal affective disorder) that works well? I've been tasked with finding one for a Christmas present. I'd prefer to stay under $100 if possible. (Honestly usually $30 is about how much I would spend on said present, but I have no idea how much is reasonable to spend.)

I think I'm supposed to get the kind that can fit on a desk easily, but not 100% sure (will confirm that).

Anyone have any recommendations?
