I replaced my PX-712A with a PX-760 and am totally happy with it. I also bought a few 7173 drives which are also very good. I bought a liteon 18x and personally I wish I had bought a blow torch since it would of done a better job! Can't speak about the pioneers, but if the current drives are as good as my 104 then buy one too. Hmm infact just buy a lot of different drives and test, its what we do
