Dixons are selling a Liteon dvd burner and one of a different brand for the same price off their internet site, im pretty sure I saw the liteon burner for £80 in store, im thinking of picking it up, is it a good buy? This will also be my first time installing my own Cd Drive, I already have 2 drives, so can i simply remove a current one and rig up this drive exactly as the old one was?
