I'm looking to buy an external disc drive for my laptop as I want to burn a few files onto some dvd-r and CD-R discs. There's a lot of cheap ones on Amazon about £10 but the reviews are mixed, some say they stop working after two weeks. I was looking at an Asus one that's £28. Is this a good make? Even the more expensive ones have got a few negative reviews so I was wondering if anyone out there had bought one that they would recommend. Thanks.
