I'm looking for a hard drive based mp3 player for my dash.

I've researched the following units:

Rio Car, Empeg: No longer in production, so they're $$$ on Ebay. I'm most impressed with this unit except for the fact the it's a pull out unit instead of a removable face, and FM is a rare add-on.

NEO Car Jukebox: This is readily available. Price isn't too bad. I've read a lot of mixed reviews from users. Seems like it works or it doesn't.

Kenwood Music Keg: I'd be willing to install this even though it's separate from the head unit.

Has anyone had any experience with any of these units?

Does anyone know of any other Hard Drive based units? Has anyone tried the new ones from Sony?

All of my music has been transferred to MP3. I transferred it so I don't have the hassle of dealing with CDs. I'd like to keep it that way in my car too.

Thanks in advance.
