Which portable gps do you use for flying/driving?

Anyone have any tips for an inexpensive portable GPS unit for
all-around use that isn't too terribly expensive ($500) and has a
bright color screen?

I've been using a Garmin GPS V for the past 5 years or so, and the
screen's so small I have to hold it close to my eyes when I want to
see details, and the screen's never been very bright, but it's not a
bad all-around as far as functionality goes. I've looked at some of
the auto-oriented models, but few seem to have a direct-to function.

I also have a Pocket PC, but don't want to spend more on software and
a gps antenna for it than I would on a decent portable dedicated gps.

Thanks!
