What’s the Best ogg- and linux-compatible hard drive based portable music player?

Dear LazyWeb: What’s the best ogg- and linux-compatible hard drive based portable music player? Unlike the old days, there now seem to be a large number of portable ogg players, but most of the mainstream computer press sites give short shrift to linux compatibility issues. So what does someone “in the know” buy? I’m interested not just in compatibility, but also a player with a thoughtful physical design, user interface, and that doesn’t have little plastic-y bits that will break over time.

(By the way, the ‘official’ LazyWeb site seems to be completely overrun with spam trackbacks.)
