True, there are many options available.
I picked up a Acer when they first came out. Had to send it in for upgrade. But since, it works like a charm. Have maps for all of Europe.
One thing I noticed when using another brand for testing, it kept wanting to send me on these gravel roads over the mountain, not on the paved roads around them
The Acer keeps me on track, is user friendly and the voice is pleasing to the ear. Warnings are well in advance, finding a location or address simple and the unit is also internal battery operated for use while on foot or incase the unit becomes unplugged!
Most of all the price is right!
Have fun shopping

PS: My HIND (Human Internal Navigation Device) is usually too preoccupied with what is going on around the car and sees the signs too late. Thus, my decision for a GPS-Navi.
