I can only tell you what I use, very successfully.
Yamaha MDX596 MD Deck > Optical Out > Dio2496 soundcard > record in Soundforge 6.
I'd say the optical out/in bit is most important. The Yamaha is a perfectly good MD deck, although won't play an MD recorded in LP modes. For that, I use a portable Sharp recorder to transfer, again via the Dio2496 but using 1/8" out to RCA phonos. There is a lesson there, If an MD doesn't seem to play, it is not necessarily a problem with the disc.
I use SF6 because I like it and runs my favourite plug-ins better than newer versions. Any basic audio editor will do the job. I like my old Dio2496, which is at least 10 years old. Superb spec; but there are probably good alternatives available for much less these days.
Hope this helps.
