Hello people. I am in the market for a portable MP3 player. I've seen different price ranges from $100- $350. Other than space capability, what are important features I have to look out for? Any advice on which one is better? I don't really know how much money I need to pay but if it's top notch quality, i don't mind getting a pricey one if it's worth it. I've read good reviews on the iPod. Is there any other comparable model? Thanks. I cpuld use any type on info on this so I will be confident paying for it.
