HP 32S II - worth buying?

[John Galt]

Having seen it when it first came out I didn't think much of it, too limited with its one line display, etc, but now I'm warming up to the idea of buying a good example of one.

I am interested in hearing owner's experiences with this calculator. Do you like it? Why? What are some caveats for someone in the market for a used one?

What, if any difference exists between models with the "white" faceplate vs. the "black" faceplate?
