I have a TomTom Go720! It is the best thing since sliced bread.
The kids use it too!(we have a deal- you lose it or it's gets stolen from your car---you pay for it)
The only downside is that is has a shithouse battery time so you really need to use the in-car charger as well if using it for @ 2 hours.
I've used it in the city in my handbag as well as a portable map..works well.
I d/l the map updates every week and you need to update it weekly to get the latest satellite positions or otherwise it can take forever for your gps to locate them and turn on properly.
I woudn't be without mine now...
d*ck Smith was the cheapest when I bought mine. Be careful of Ebay where some of them don't have Aussie maps.
