You make very good points.
I would love to get it going, but as you describe, I'd then have a crap CRO, with much of its appeal lost.
I hadn't considered that, being too eager to just see a trace on the screen.
I think I'll probably not ignore your post, and just clean this thing up a bit. (Not sure about a glass case, though.)
And then I also don't have to consider the selenium issues.
Thanks for the reality check!
(There's lots of other junk around here that I could be directing my energies towards instead...)
