The 2nd generation Sony DVD writer (DRU-500A internal, DRX-500UL external). Writes to all common DVD formats (DVR-R, DVD-RW, DVD+R, DVD+RW). The exception is DVD-RAM which is dying anyway. When using write-once blank media, make sure you read about other people's experiences in various forums so you don't end up with expensive coasters. You can get blank media at a much better deal online than your neighborhood electronic store.
