for a good outline on choosing a tape deck.
To transfer your old tapes ideally you'd want whatever was used to record them originally. Nakamichi decks may not suit you because their head gaps are different than other decks and Naks use a lifter to displace the tape's pressure pad. Tape traders (dead heads) talk lots about compatibility. Search a little and you'll find more than you ever wanted to know about vintage taping and reproduction.
