I'd wait a bit if you can. Rio Karma 2 is coming out as is a new iRiver. When these hit the streets, they oilder ones will drop in price.
Creative just came out with the Zen Touch Ipics @ amazon, a preview @ IGN). Has a touchpad and 24 HOUR BATTERY LIFE. Not to mention the battery is user replaceable.
I'd watch out for the Karma if you do need to buy soon, poor build quality.
