OK, here's the scoop. I'm going to Ireland in about a month.

I do own a GPS, a little old school etrex which I use when I need it.

I don't own a vehicle nav system.

It's been reccomended to me that I have GPS nav when in ireland, thanks to their perpensity for building things rather randomly after the vikings kept burning it down.

So, I have a choice:

1) Just rent one with the rental car in ireland... probably a hundred bucks. (probably the cheapest, but what fun is that)

2) Buy a small portable handheld that can dual purpose as a gps and car nav system with loadable maps, *and* load it with maps for ireland...

3) Buy an actual car nav system and maps for ireland the same same..

Any thoughts on 2) or opnions? reccomendations?
