I have using Liteon ever since the CD and DVD - no problem. Sony ok, Samsung and LG stay away from them. For blu ray Pioneer and Plextor were known good but I haven't brutally used them yet I say that cause I burn a lot of disc of all sorts and reliability is my priority specs.
I have had a Liteon in my computer for 7 years now and it is just finally starting to have occasional issues of discs slipping and sometimes jamming when it ejects them. That being said, I have seen many posts recently about the Liteon drives not being plug n play with Window's 7 64 bit unless it is manufactured after Dec 2009. Double check the manufacture date before buying it. Sometimes hardware a couple of years old can make it onto someone's shelf or warehouse.
Just as well I should say that I just ordered the Plextor PX-B310U external Blu-Ray drive. 2 reasons... I just built a micro lanbox that I will be putting up on a hutch over my desk to free up desk space and this will let me keet a small drive under my monitor. The other reason is that I have yet to see a single internal Blu Ray drive that is not having problems once they get a large number of reviews under them. For some reason the externals seem to be more stable. Yes I know it is a 6X, but the Plextor externals are about the highest rated in the industry right now. You can also stick it on any computer you want, including a travel laptop.
