OK so this thread has piqued my interest in buying a GPS system. I currently live in LAX, thought probably don't need it for driving around the LA area. I often travel to Europe with mainly walking but also driving in countries such as Italy, UK, Finland. Will also be moving to Australia. We will be on a driving holiday in Ireland in July where it would also come in useful.

So I am interested in something I can use in both cars and handheld, have maps for US, Europe, Australia, and be the most cost effective balancing basic functionality (though the street naming feature sounds nifty).

Given the above considerations, and over and above the comments already made in this thread any other suggestions (especially given cost of acquisition plus additional maps or whether maps included).

Thanks
