Hrqls, I would spend the money to make sure you get the features you want. Such as downloadable maps. Also, get one before you need it so you can have the time to learn how to use it. You can go to http://www.geocaching.com for some fun exercizes to help you learn how to use it.

I've only used one once. When it says it is for the US market only and uses the WAAS...does it only work in the US. Isn't the WAAS a US based network?
