Where can I buy a creative zen vision m 30gb? How much will it cost?

Where will it be the cheapest? Or where can I fix my old zen vision m 30gb? I live in South Africa. So I want to buy it here if possible? I have a creative zen vision m 30, but its broken! It don't wanna charge or turn on! It worked fine for about 2 years. My pc detect it in device manager under other devices? Do anyone know how to fix this?
