Sony DVD Writers

[Howard]

I am interested in buying a DVD writer. My research initially suggested that the Sony DRU500A was the best choice for my application. However, when I tried to purchase one, I found no stock at all vendors I contacted. During my search I discovered that a "new" model, the Sony DW-U10A, might be replacing the DRU500A. However, I can not find stock on this item either. More than one vendor suggested that there was manufacturing problems with the DRU500 and that units were recalled. Can you please tell me the "real" story about these drives? Thank you.
