Just starting to think about getting a Garmin Edge of some sort but not sure what to get. I'm not riding with power and don't anticipate doing so and I won't be syncing it with any other gadget other than a computer so I'm thinking that I should exclude the 810 as the best choice. I'm thinking the 800 might be the one for me but still not sure. I see that for an additional charge, "maps" is included. What exactly does maps mean? Don't want to pay for something I don't need. Thanks for any input.
