I was considering getting a GPS but I am a bit confused by all the options and terminology. I would use it when I hike into the national forests to find a particular spot but mainly to help make sure I can get back to my car. I might also use it when I kayak around some of the larger lakes to make sure I know the way back. I do take a map and compass though I thought a GPS might be easier.

Since I would probably only use this a couple of times a year price is a consideration. However I don't want to spend some $$ then realize it doesn't do what I want it to do.

I see Walmart has 3 Garmins for $119 and many more for much more $$. One big question I have is about maps. Some say they have a basemap others don't. I also see that you can purchase maps +/- $100. What is the difference? Do I need the maps? It seems it would be useful. Memory, I see 8mb up to microSD cards which I suppose you could get 16GB or more. That is a huge range. What do I need?
