Portable usb dvd/cdplayer/cdrw drive

Dear All, Does anyone know of a reasonably priced portable usb dvd/cdplayer/cdrw drive that will work on both a Compaq Presario 1700T laptop with Suse 8.2 and a PC with Suse 8.2? I want to use this for watching dvd movies especially on my laptop. Thanks, Marcia
