Seeking input

A reader posted this on my Canning Bacon post, and I thought I'd bring it up front.

I have a general canning question... I am planning on spending my Christmas money on a pressure canner. However, I've been reading that pressure canners should not be used on a glass top range. Is this true? Or just more internet hype?

I am totally unfamiliar with glass top ranges so I cannot speak at all on this issue. I welcome reader input from anyone with experience canning on these ranges.
