Good old, good new DVD writer - recommendation needed

Hello,
I need to buy a drive that provides very good recording quality on the good media (mostly single-layer). This may be new or used device. What do you recommend? Good recording quality on CDR is also welcome.

AK

Read through this thread from last year and you should get a better feel for those models that were well respected in the past and what is available now. http://club.myce.com/f61/state-optical-media-writers-march-2015-a-338479/

Thank you for your answer. There is a lot of information, but my needs are more specific.
