I suggested the MD primarily because I thought it was probably closest in functionality and interface to a tape deck, at least to a cassette deck. It's capable of making a perfect digital copy so the sound of it will be as good as the digital original played back through the same system.
A reel to reel deck would be a great way to preserve the analog character if you're recording from a turntable and that sound is important to you. It would be less convenient but if leaving digital out of the equation is what you want, it's a good way to go.
I haven't used the Tascam, Korg or Alesis units recommended by Ajahu and Dopogue but I'm sure they have their own advantages. CDR and CDR-W blank media are going to be easier to find and cheaper than minidiscs.
