Guys, I know you know this. What is the best and most affordable GPS system. I have been looking at the Garmin EMap. What are your thoughts on this. I dont have 600 or even 1K to spend. But I do have a couple hundred. I didnt know if I bought a low end one if I could load maps, and if they were readily avaliable, or not. Also, I would like to have Speed, elevation, and compass on it. Thanks for all your information.
