Pioneer 111 easily gets my vote. Buy Verbatim 16x DVD media and burn at 8 or 12x and you will never need to "scan" your media since it will always be burned with good quality. You can always do a Transfer rate test to see if the disc is readable.
Scanning is very overrated here on these forums. Good "scans" don't even mean the disc will work in a dvd player. If you start scanning you will turn into a scanning junkie like most of the other people on this forum and exaggerate when you get a disc that slightly scans worse than another.
Scanning is not 100% accurate and it doesn't reflect how well your dvd player or whatever will play the disc. It is displaying how easy it is for your liteon to read.
I have a liteon and I can say that the pioneer writers have always been good, whereas the liteons definitely haven't all been good.
The choice is yours. You can enter the dark side and scan stuff and waste time only to find your disc does work and they all work and scanning it was a waste of time. Or you can just burn with the 111 and be happy everything works without problem and never bother scanning things non stop.
Even a person like me who is skeptical about scanning media, still scans every burn! It's a bad addiction
Oh and let me tell you one last thing, liteon drives tend to get different scanning results from model to model and even firmware can affect the number of errors a scan shows. How the hell can that be accurate if they are all different? More accurate scans come from professional equipment, and the results from those don't really agree much with home scanning.
