I hate to open yet another 'which one should I buy' thread, but after spending several hours scouring ADV rider and other forums I am still truly lost. I am looking for a cheap/budget unit, but I am not afraid of used or refurbished, ebay or craigslist, anything to get a deal. The unit would mostly be used for retracing my tracks when I get lost, or for loading a days worth of logging roads from google maps or a .gpx file from a buddy to follow with points of interest marked before hand. I doubt I will use the unit in the city (as I tend to prefer good ol' paper maps and getting lost) but I would like to get some vague directions through a foreign city to visit a friend or whatnot. I dont need incredible detail, color is not necessary, and I have young eyes so screen size is not paramount, but I would like to be able to see the majority of service or logging roads so that I may follow them. Waterproof seems to be something everyone is worried about, but I dont think i'm too worried about that. I rarely get water above my knees and if i'm dropping the bike in water that deep then messing my GPS up is not the worst of my worries, but I would like it to be foul weather proof. I dont care too much about voice directions as I wear ear plugs, but it might be a nice addition if the cost difference is not overwhelming. And finally, to sum things up, I would like a GPS unit that would allow me to ride somewhere I am not accustomed to with its tracking on so that I may find my way home after taking a dozen incorrect turns and several miles of tight trails or other unmarked roads. I already carry a SPOT to comfort loved ones and to call in the cavalry to get me out of any tight spots I may encounter on a solo adventure. I appreciate any responses, and I will continue to check any local electronics stores for sales.
