Well, I haven't seen either, but a backlight will usually reduce the
visability of the LCD in normal light, the only time it will improve
the visability is when you use it in a dark area.  If the screen contrast
is worse than a typical 85 I don't think I'd recommend a backlight
unless you already have something better to put behind it.  An EL
backlight probably would not be a good idea.

I remove the plastic screens on my 85's, it makes the LCD much
easier to see, the plastic is kind of hazy, and any covering will
decrease the visibility.  It doesn't look as nice of course, but that
doesn't really bother me.
