Suggest the best ripping dvd rom to buy

liteon the 163 model - is it available?
is plextor premium cdrw available?

L 163 is long time obsolete…

I’d go for the Liteon 1635S DVD-RW. It’s a very good reader of poor quality disks , very good disc quality scanner & a pretty fair burner as well. Does a good job burning CDs.

It gives you the option of another burner that might do better with some media than your existing burner.
