Seeking feedback: Which light table would you recommend?

Last month, I moved from Houston to Chicago. In the move, a rather sad thing happened: my light table, my trusty little Artograph light tracer, died. Not only did the surface crack, but the internal bulb died. I've had that little portable light table since art school, and it's always served me well; now, however, I'd like to replace it with a bit of an upgrade. I'm looking to spend more than the $35 I spent on the original Artograph, but less than $250; I'd still like something portable/lap-sized that I can curl up with comfortably. I've found a few prospects that I'd like to try out, but what would you recommend? What's your favorite brand/style/size of light table for home animation?
