I'm going to transfer a batch of cassettes to high-resolution digital, looking for a top-of-the-line deck that can capture just about all there is to capture off cassette tapes. Some will be pre-recorded music cassettes, but mostly privately-recorded personal stories.

The Tascam 122MkIII and the Nakamichi Dragon have come to my attention. Would you recommend one over the other, or something else?

A guy I know that works with a lot of tape mentioned the Dragon has automatic azimuth adjustment, which apparently is its claim to fame. Availability of parts and service are important too. They still make the Tascam as far as I know.
