I just bought the ASUS External Slim DVD-RW, Model: SDRW-08D1S-U

I bought this unit because I now had three micro PCs or laptops in the house without optical drives. Unless pre-installed, kinda hard to get an OS on them without one of these. I bought it from my friendly neighborhood Best Buy. They had a couple different makes/models. The ASUS price' was about midrange ($65) and I've never had a problem with anything else from ASUS, so...

The package contained the optical drive, a stand, driver disk, instructions, and USB cable. The only way to power the device is via the double-ended USB; I would have thought there was an external power option or adapter included, but no.
