Here's a rather perplexing situation - the pair of HP burners are apparently both new (to this retailer), and the price difference is $10. There is, AFAIK (from the descriptions), NO obvious feature difference. Both are SATA, support LightScribe, support DL media, support 24X maximum burn speeds, etc. Would purchasing the less-expensive drive (for the PC below) be a mistake? (This would be my first SATA optical drive, but would *not* immediately replace my existing PATA optical drive.)
