Garmin Zumo 550 gets my vote. I bought one two years ago and it went through rain/snow/heat without a problem attached to my SprintST, and now it sits on the Rocket III with 500 songs on it (since it is also an MP3).
I've got a Garmin Nuvi and haven't had any issues with it. I did need to install a 12v as the battery life is only a few hours, but my wife got me this sweet mount for it (most are real ugly) that I get compliments on all the time.
