What DVD writer DL do you feel best

Now that I had experience with almost four brands of DVD writers,
Sony, SSung(TSS), Acer, Pioneer, all of them are having something or other
negative. Most of the CD writers life is limited to hardly one years of operations
after which it is better to throw.

What is the reasonable DVD writer DL I should go for. Some people who are using them may please be kind to post their experience about their respective model. It will be very helpful to all who wants to buy a new or wants to replace.

Thanx in advance
