Hello. It seems like there are several types of Liteons here. Well a few months ago I was looking at new burners, and decided between the LiteOn LH-20A1H and the Pioneer DVR-112D. I picked up the DVR-112D and it has worked all right.
Well, I now think I am ready to replace my old LiteOn 6s with a newer version.
Here is where I need your help. Could anyone tell me which order they were released and which is best? I know of the 20A1H and 20A1P, but I have also seen the DH-20A3H and DH-20A4H I believe.
