Many Lite-On CD-ROM and rewriters are rebadged from other manufacturers, including Plextor: click here
See: click here for details of most drives and rewriters' original manufacturers and which are rebranded.
There are also hundreds of articles on any subject to do with these products and their media.
My forecast is that DVD rewriters will continue to come down in price steadily - they are already nearly half the cost of a year or so ago - along with the media used with them.
But it's the old, old story - if you choose a product and wait till the price comes down, something even better comes along; in the end you never buy anything....:-)
