Have you owned a BenQ?
As with any hardware at a forum like this you will hear the good, bad and the ugly
I own BenQ1620...got them very cheap and for the price they are great
I personally think the Nec35xx( some report the 3500 is better than 3520...I have no experience..is this true ?? media compatibilty), LG burner, Benq are all good choices
I would go with the cheapest of those availabe to you and where you can get the best CS..since the prices for you are higher than in the US(Nec, Benq go for $50 or less with some sales...not sure on LG)
For me not sure the RMA is worth it if the $40-50 drive dies by the time shipping and time is added in....@$100+ different story
