Im on the market for a DVD writer. Currently my supplier has these in stock ?
NEC ND3520A 16x
Pioneer DVR109 16x
Samsungs TS-H552 16x
All drives are dual layer.
The Pioneer drive is slightly expensive than the others.
Which do you recommend ?
I would go for either NEC or Samsung… both make excellent drives. Where-as i’ve never used pioneer so i dont know anything about it. I am positive that either one of the drives i mentioned will make you very happy. Plus, they cost less! Hope that helps even though its only narrowed down to 2. Good luck! 
Pioneer makes excellent drives, haven’t had any experience with the NEC’s or Samsung’s but I have an A03 and an A04 and both have served me well.
I got the Pioneer DVR 109 drive.
What software do you use to burn DVDs ?
Nero Burning ROM 6 to burn new ones, and CloneDVD to copy them.
Where can I get DVD Clone ?
