I use a Nomad Jukebox 3. Does DAT quality and has easy USB or Firewire trasnfer to your HD. Its not the greatest recorder, but it works. It'll run about $200.
The next best would be a Sony DAT, and a bit perfect soundcard, like an Audiophile 2496. This combo will run you about $500, if not more.
If you aren't concerned about size or price, Marantz offers a HD recorder, as does Fostex.
And then there are the Sound Devices...
