There are no "best" writer on the market, as every claimed "best" writer has its own short comings. The only way to get the best is if you buy a Lite-On, Asus, Plextor, and Yamaha.
For me, the best choice would have to be the 52x Lite-On since it's affordable, defeats a load of protection w/ the appropriate software, and has the most frequent firmware updates.
54x writer? Where?
