I'll vouch for the LiteOn 166s DVD ROM, as I picked one up for 20 USD...
I threw a CD (Audio) across the driveway 4 or 5 times, scratched the living daylights out of it.... but the LiteOn read it like it was nothing....
Also tested the worst possible scratched DVD I could find, and it ripped it just the same, slowed down a bit to just 8X but it did rip it fine...
