That explains why CRTs are so heavy!

Edit: ..since they're filled with liquid crystals.

Hmm... sounds like they got the model T (100) and model P (4P) confused a mite....

Actually, I'm pretty sure they got that wrong. LCD (or "normal") monitors are liquid crystals. That's what LCD stands for: Liquid Crystal Display. CRTs are heavy because the system required to make the Cathode Ray Tubes display images is huge and heavy. For more information, check out Wikipedia.

The weight of a CRT display is almost entirely in the glass.

Is 150$ a good price for these? Seems a bit expensive in my opinion... Then again it is the very rare LCD version
