I can't make up my own mind and you want me to make up yours??

That's why I haven't bought one yet!!!
Ok... for your price range...
What you also NEED is a lit screen, or you can't see it in the dark! Anti glare is nice too... long lasting rechargable batteries... but about 3 hours is all I can find on this price point. Some have 6 or 8 which, as I get lost in a city, is what I would need (say I wasn't in a vehicle.)
http://www.magellangps.com/products/....asp?segID=354 Look at this one and see how it compares. That you can add your own addresses is nice. It also provides phone numbers of destination sites, so you can call them ahead of time.
Alerts for when you are nearing your destination, or for items such as school zones and security cameras are kewl too.
You do realize you need to sign up and pay for activation, right?
If you can go a bit higher in price, look at the StreetPilot C330. At least you can see some of the things you might want. Not knowing what's available means you might not get what you need (like the hsn product?) To determine the features of the HSN products, you need to call them and ask for all the details. What they are displaying in the ad is not enough info, for me.
