Holiday Gift Idea: Portable GPS Unit

I'm thinking of this kind of device for er, someone I will not name here (it's actually for two someones). These people love to travel so the interest factor is there.

I found this model at Amazon. It's a decent price and well-rated, but even Amazon admits there are some issues with it. But if there's nothing better, it may very well be my choice, or I may end up getting something else (e. g. not a GPS Unit). But let's assume right now that a GPS Unit is the thing.

Here are my parameters, more or less in order of importance:

1. Price. Nothing above $300, and preferably under $200
   
2. Must be a voice unit, e. g. it tells you how to turn. I don't want anyone to have to read while driving. A headset or earphone is a plus for walking.
   
3. Ease of use. I don't want anyone to have to carry around a user manual after the first few usages.
   
4. Display size. Tiny print won't cut it.
   
5. Portability (which conflicts with display size, I know). These people both drive and walk, and might rent a car in a remote location. I'd like for them to have all of these as options.
   
6. Ease of getting service on the unit. That usually means a brand name. These people live close to a large town and fairly close to a very large city, but I'd rather that they didn't have to go to the big city if the unit needed repairs. Hence something that's also sold (although I wouldn't necessarily buy it there) at a place like Best Buy.
   
7. Ability to enter and save specific addresses (e. g. a friend's house or the museum or whatever). Not a deal breaker; this one is in the category of "nice to have". I think I can live without it if other needs are satisfied.

So -- A2K shoppers -- what do you think? Is the above item a good buy or can I do better? Oh, and another thing -- this is for Chanukah, which comes a couple of weeks before Christmas this year.

Thank you.
