alright i've seen a few varieties of these car harddrive MP3 jukebox type things:

neo car jukebox ranging from 20 gigs to 120 gigs (not a HU)
sony has a HU that has a 10 gig HD
i think panasonic is coming out with a HU with an HD
there's a company called phat sounds or something like that phat audio, that has a similar thing as neo's car jukebox

i've heard great reviews on neo's car jukebox,
i'm trying to find the cheapest prices.. and if there are any other ones that are cheap and worth it

thanks!
