OK, so it looks like either Tom Tom or Garmin are the way to go. Avoid Magellen.

Does traffic cost extra on all of them?

Traffic is extra on TomTom, I know that.

One bright spot is that user-created voices are free (I now have Kitt and Darth Vader, thanks to Lash)

Yes, traffic is a subscription service on all of them.

Make sure you get it somewhere with a good return policy. You won't know how well you like it until you're actually in the car trying to follow its directions.

Thanks everyone!

I think you should get the Tom Tom so you could sing this all day long:

What you gonna do when you get out of jail?
I'm gonna have some fun
What do you consider fun?
Fun, natural fun

I'm in heaven
With my boyfriend, my laughing boyfriend
There's no beginning and there is no end
Time isn't present in that dimention
He'll take my arm
When we're walkin', rolling and rocking
It's one time I'm glad I'm not a man
Feels like I'm dreaming, but I'm not sleeping

I'm in heaven
With the maven of funk mutation
Clinton's musicians such as Bootsy Collins
Raise expectations to a new intention
No one can sing
Quite like Smokey, Smokey Robinson
Wailin' and shakin' to Bob Marley
Reggae's expanding with Sly and Robbie

All the weekend
Boyfriend was missing
I surely miss him
The way he'd hold me in his warm arms
We went insane when we took cocaine.

Stepping in a rhythm to a Kurtis Blow
Who needs to think when your feet just go
With a hiditihi and a hipitiho
Who needs to think when your feet just go ...Bohannon Bohannon Bohannon Bohannon
Who needs to think when your feet just go ...Bohannon Bohannon Bohannon Bohannon
James Brown, James Brown
James Brown, James Brown

If you see him
Please remind him, unhappy boyfriend
Well he's the genius of love
He's got a greater depth of feeling
Well he's the genius of love
He's so deep.

Huh?

I love my Tom Tom (tom tom 0ne, Version 3) and if you ever needed a map of Australia.......

Oh, go look up "Genius of Love"

I would be shocked if you hadn't heard the song. Absolutely shocked. You're from SoCal, right?

That's what I have! :D What voice do you use? I'm partial to the men with accents (Irish in particular).
