Sandisk makes great ones. I have a Sansa Clip, (a 1 gig version), but they come in up to eight. It blows the Shuffle out of the water, partly due to the fact that it has a screen and doesn't just randomly cycle through the songs on yer player. Other players Sandisk makes are good, too. They tend to take a lickin' and keep on tickin'
Also, things that Samsung, iRiver, and Sony are good as well.
