Welcome to CDF’s:
I doubt you could find that older drive except for maybe ebay these days. Here is what members here picked for top drives of 2008 > http://club.cdfreaks.com/f61/top-5-optical-drives-2008-cd-freaks-members-choice-249785/ again some of these top 5 drives cannot be found easily.
What is your location? You want external drive? IDE or SATA? Media also plays a big part especially with DL discs. Do you have DL blanks already?
