Here is the topic with the write-quality of the 209:
Pioneer don´t manufacture the drives by itself. They switched to QSI some years ago.
Imho there are max. 3 manufacturers of BD-writers atm, LG, QSI, Panasonic; Panasonic only offer slim-drives AFAIK.
I own the BDR-208 and it´s one of the best BD-drives I ever had when it comes to write-quality. Only my old LG BH10LS30 is a competitor.
Quality scans are not possible with Pioneer-drives.
The Liteon-drives are AFAIK are all EOL, maybe you find some to a horrible price or used ones.
But I can tell you these drives are far away in write-quality of Pioneer and LG, thats my experience.
