In daylight, auto exposure generally works fine. I was speaking of
working with difficult indoor light. Indoors, the LCDs generally
work fine.

My Nikon 990 and D70 both have a feature that causes blocked-up
highlights to blink in preview mode.

Since there's no film nor processing cost associated with making digital images, it is generally more reasonable to just bracket exposures (take several shots at different settings.)
With most digital cameras, an external light meter is pretty useless,
because most digital cameras have zoom lenses that change aperture
("f stop") as you zoom.
