A garmin e-trek should suit your needs...
I feel Garmin is the most intuitive and user friendly...
Magellean is the worst to me... I have one here that is useless...
I cannot even toggle to "course/track up" from the "north up" mode which means i am usually flipping the dern thing upside down and looking at upside down data...
I will make you a great deal on this little barely used color screen GEM...
