I bought the last burner I have, about 3 or 4 years ago at wallmart, everything but Blue Ray, for about a $25 dollar bill. Internal, sata interface. It has to date burned 2 or 3 100 count spindles of cd's and dvd's, and has never hicupped unless the disk was phony. Some brands have a high phony percentage.
