I have a LiteOn DVDRW shw-1635s. Burns +, -, r, rw, dl. Rates good. Burns great. You can pick up one for around 25.00, us. Wallyworld had this for 25.00, Sony for 35.00. Search for revirews from consumers, you can get an un-biased opinion of what works and what doesn't. EDIT> It seems that the media you use is more "much more," important than the burner. You can have the best burner on the market, but will spit nothing but coasters with poor quality media. Search for media in the forums. There is a wealth of info.
