I just bought one from Staples. It is fine, but a little big. The external CD-RW is much bigger than the internal. Since my notebook is USB 1.1, the speed is only 4X. slow, even though the drive is suppose to be 40X with the support of USB2. Only the lastest notebook comes with USB2. My suggestion is to buy the cheapest one, the slowest one. How fast is meaningless if you only have USB1.1.
