there are many places on line to get the mitsui's, just go through a search engine and compare prices. As for quality I have copied over 200 cd's and I have found by comparing directly with the discs going at the same time you virtually can not tell the difference. I have found that the main thing is to first copy the disc onto a hard drive and then put the music onto a cd-r, that way you are not dealing with buffer zones. On scratched discs this can become a problem. It once took me an hour to upload a 43 minute disc with a bad scratch that played perfectly on my cd player. And you could not tell the difference in a straight comparison.
So much on sound can be subjective but if you record your discs to your hard drive first and have somebody else handle the cd comparison test and all you do is listen you should not be able to tell a difference. If so maybe you should submit a resume to Steve Hoffman
