Yep they both play songs.

My daughter has an MP3 player with 512mb memory. She can store about a hundred or so numbers on it.
The beauty of it is that it is small and slips into your pocket and you use headphones to listen to it.

Remember the old Sony Walkmans. Its a bit like that really.

>>does one do more than the other and what would you recommend? <<

Yes they do, and it all depends on price. I wouldnt dare recommend any particular model. The product most in demand is the Ipod and is expensive. I personnally think there are equally as good products on the market other than Ipod, and cheaper.

Just like buying a computer, you need to ask yourself, exactly what the purpose of your requirements are. Armed with that info, go to somewhere like PC World and get one of their techie guys to give you advice (plus/minus) points on their models. Don't buy immediately, go away and consider what you have been told.

Once you have got a few models that might suit your requirements, search for them on the Internet, to find the cheapest supplier.

EBay has a lot of of MP3's but you need to buy from a reputable UK supplier, not soembody from Hong Kong etc.
Some will offer a cheap model and then charge you twice as much as the unit itself for delivery. You need to add all the costs together to work the final cost out. One of the problems with suppliers from Hong Kong etc is long delivery time, with very high dleivery costs, and people who are so far away.
Only buy from top rated dealers, or you may never see your MP3 delivered.
