I am thinking about buying a used laptop for my music collection which is at about 15000 songs. I will also take it to the bar so it's playing music for 16 hours a day. I have a Dell inspiron 1520 that is 3 years old and has been faultless so far. I have seen the Inspiron 1720 model on ebay for around 250 quid. Or should I look at other brands. Has anyone bought re-con or used laptop this way?
