Wanna save a bunch of money?
I've owned two Garmin units over the years.
I ditched them both and now run the ViewRanger (GPS) app on my smartphone. The app cost $14.99 and works as well/better than either of the Garmin handhelds that I previously owned. Great features and very accurate. The app does not require cell service to work... runs off satellites. Many many many maps are downloadable for it (Nat Geo topos, etc.). Can run the app on tablets or smarty phones. Battery life of your device is the only limiting factor.... I use a Moto RAZR MAXX so battery life is not an issue.
If you have your heart set on a Garmin, go for it... certainly not necessary. I like this app better than either of the Garmins I've owned and will never look back.
