I bought the Novatech one, you should be able to find it on their website click here. Its just over £40 if I remember rightly and takes smartmedia cards. Warning about the smartmedia cards, once you format them for the MP3 player you can't use them on anything else but since they're fairly cheap its not a problem. I bought a smartmedia card and a set of rechargable batteries from click here as it does tend to go through quite a bit of power, you get approx 3 hours play out of 1 battery. It plays perfectly and I'm very happy with it.
