I use a 160gb iPod Classic. The connection is a bit flimsy, the sound isn't the best and it has no native FLAC support, but the screen is nice and bright and it's big enough to hold most of my music. If you're looking for high capacity/small size, this is the one. If you're looking for sound quality, a Creative Zen is better. Video quality it has to be an Archos. It all depends what you want it to do.
