Buying a burner for ripping...please help!

Hi there, I am trying to choose a DVD writer that will help me back up my DVD movies. I simply want to be able to copy movies using probably SHRINK and NERO. Which DVD burner would be my best choice…there are so many mixed reviews.

Leaning towards:

NEC 3500
LG 4160
BENQ 1620

Help please! My head is spinning with all these features and terms. I have been doing my research, but I am not sure which is the best for my purposes.
