cdrinfo.com has a head on review with the liteon vs plextor. Honestly neither one comes out on top, they are almost the same in performance and features with a few slight differences. I have the liteon burner, its my second from liteon, my 4th overall, and its the best one I've ever owned. They do frequent firmware updates, the drive rips audio fairly quickly, is GREAT for copying cds, checks the quality of the cd so as to prevent buffer underruns, of course has a burn proof type protection, and overall just works fairly flawlessly. I use it with Clonecd/Nero/Cdrwin mainly, and all programs work fantastic with it. I may sound like im trying to promote it, but the drive is just really good, the best for the money IMO, and trust me, I use the drive extensively for much more than "casual" use. Probably burned about 100 cdrs so far, not a single failed burn, using all sorts of media. Anyways...just get it.
Don66: Could you be more specific, like RMA issues, or your drive just broke fairly quickly, etc...? I probably went through about 500 burns on my 12x Liteon without any issues before I sold it for this one.
