OK, so I want it all.
I am an engineer and have been using a laptop and Earthmate DeLorme portable GPS pluged in to my laptop for a couple years now. I really like it when I am in my truck out in the field hunting or doing engineering.
So much so, that I would like something that is "portable" and doesn't require tons of batteries and wires. I would like to be able to use it for big game hunting and while hiking. I really don't want to give up a map base that shows me where I am with topo and road features. I don't mind adding an expansion memory card (I have serveral for different digital cameras.)
Now, I would also like to get something I could use as a tourist in Europe. I have seen that many allow you to download maps and some of the map packages include other countries outside of N. America.
From my perspective I really am tired of lugging around a laptop when I need to gather GPS data and would never take it on a vacation. However, I would like something with much of the capability I am use to.
I have looked at some of the PDA & pocket computer GPS stuff, but they don't look all that more powerful than a straight hand held GPS (although they have a slightly larger display.) Some of the antenna add on-GPS units for PDA's look like they eat batteries as well.
If I wanted to get something for the back-woods and the streets of Rome, that was a handheld GPS with decent life per battery charge, so I could find both a deer stand and the Vatican, what would your recommend if I wanted to spend less than $500.
What would you say are the critical features I should consider.
Thanks in advance.
