I have read and read, asked many and it seems that a few are mentioned always at the top when i ask. It seems almost everyone loves the Pioneer DVR-111. The LG H22N is another one that it seems most all really like. Some like the LG H22L with lightscribe but some say it is not as good as the H22N that has no lightscribe. Lightscribe is a way to make labels without your printer and labels. The media usually cost more.
Are you going to get one or two burners? It seems that always Benq is rated very high and what i read all three of those seem to burn alot of differnet kinds of media good. The Benq's are getting hard to find like the 1640, 1650 and 1655. I am just getting ready to put two new burners in mine over the weekend. I can not tell you from personal experience as i have no idea but alot of people has told me to get these.
Check out the link Ian posted and also check out this link as they are also voting on the best drive here.
It sort of seems it is no perfect drive but alot of them are very good depending what you use it for. I would think the Benq, 111, and H22 would be very friendly and good for all around. It seems that Lite-On get's mixed reviews from alot but also some rank them very high. One last place, go over to Newegg.com and click on drives and read the user reviews and you can see sort of the favs on Newegg, that people are and have bought.
