Sony RDR-GX300 DVD Recorder
This machine is great!
After having a bad experience with a Sanyo DVD Recorder (many problems with recording, reading discs, and, finally, it wouldn't even read pre-recorded discs!), I bought this unit.  It is easy to setup and use and it actually does what it is supposed to do!  And it uses any of the + or - discs.  Even in the slower modes, the recorded picture quality is excellent.  I good buy and highly recommended.
