I have some extra money... I was wondering what would be nicer or more practical in your opinions. Try to keep it around maybe $700 or less

GPS:

GARMIN StreetPilot Series $399-$500

or


MAGELLAN RoadMate Series $380-$500

In-Dash:


Jensen Multimedia $700



Something along those lines. What do you think is more practical or better. Like do any of you have good success stories or rant stories with GPS or anything?

Thanks
