I have a Magellan I can't remember the model but it really doesn't matter. I think any name brand will work fine. I would definately buy one with mapping capability and one that at least has a base map of the USA. If you want to buy mapping software make sure it has enough memory or else you won't be able to use it very well. The first unit I bought worked great but it didn't have a base map. You could only see points you marked. The new unit I got last year has mapping software and it's pretty cool to see where you are in relation to nearby roads and other landmarks. Even if you don't buy any map software make sure the unit has a base map, it will make your life easier.
