This is my first post so forgive me if anything goes wrong! I have been "lurking" here for several weeks collecting information to help me choose an external burner to use with my laptop - you guys sure know a lot!
Anyway, on the subject of this thread, I have seen an HP 740i here in Hong Kong. It is a faster version of the 640i with the following specs from what I could see: DVD+R 16X, DVD-R 16X, DVD+RW 8X, DVD-RW 6X, DVD+R DL 8X, DVD-R DL 4X. It has Lightscribe.
The one I saw is an internal version and costs about US$78.
I tried "Googling" it and the only sites were asian; most seemed to be Korean.
I have no idea what burner is inside. The 640i here has the Benq 1625, I believe.
May be worth checking a bit more before scratching that itch, hellsat!
