I actually do have a CRT, but only one, and they're impossible to find for a reasonable price new, these days. And considering they fade, I wouldn't want to get a used one.
EDIT: And as Dan mentioned, I'm not sure they're any better.
PS Are there options when buying glasses to have them specially treated, does anyone know? I do need to get yet another prescription (in less than a year, I believe), I'll be asking when I go. I was just curious if anyone had any experience with it, or if it's not worth it.
