the top two burners (IMO) right now are the NEC-3500A and the Pioneer DVR-A08/108. if you can wait a few more days, plextor is coming out with their 16x writer, the 716. while all of these drives are available as internal drives, the cheapest way would be to buy an external enclosure (usb2 or firewire) and put the dvd drives in them. the enclosures can usually be had for cheap off ebay, and newegg usually has good deals on them.
