LTR-52327S+LTD-166s or Plextor Premium alone?



I am buying new gear after been dissapointed that the LTD-811s could not burn DOOM3 last summer. I have come to these 2 options:

Litey LTR-52327S paired with LTD-166s DVD-ROM


Plextor Premium as spurce-reader/burner only.

What will offer me a better all-arround solution against last protection versions backup, specially Safedisc? Price is not a factor.

My burnng program is Alcohol 120%.

Thank You.
