Looking for a new GPS

[rob85635]

I have the Garmin 700. It works but does not have all the features I want, a $99 upgrade dvd is available but I don't want to buy it so I'm looking for a new one.

Here is what I need it to do.

1. Give me Lat/Long (duh) and elevation
2. Have the ability to mark a place my vehicle is sitting and give it a name. I ghost town hunt and occassionally I come across a neat old broken down home, a cool photography spot, etc.
3. If possible, not sure they make it, a GPS that will chart the dirt roads I am on and remember them. For instance I can turn on the "mapping" or whatever and drive. Then when I am done I will have a line (much like a new road) on my gps that I could name whatever I want, say "dirt road to the old well".
4. The rest of the normal stuff.

Recommendations would be greatly appreciated. If #3 is not possible I must have the ability to add my own points of interest.

Thanks,

Rob
