The 670, I own one, it rocks! The sweet thing about the 670 is you can do breaks on the fly. What that means is, if you're recording along, and you want to end what you just recorded and start a new file, you simply hit the Record lever again and the file is closed and a new one opened, seamlessly. The 670 produces WAV files, and you will need a Compact Flash reader to use it with a Mac (i.e. the Lexar FireWire based one for $60.) See me in-progress review of it here: http://sldghamr.faithweb.com/PMD670.html The price of CF media will kill you, but the recorder is $700 typically on the street. In stereo uncompressed WAV mode you will get around 95 minutes on a 1GB CF card. So to get 3 hours you weill need 2 - 1GB CF cards, that will run you around $850. If you can make due with slightly compressed audio the 670 offers 384kbps MP2 (MPEG 1 layer 2) recording, which is pretty darned good for hobbyist and semi-pro use. That will get you almost 3 hours on a 512MB CF. It also offers MP3 at bitrates up to 320k, but at high bitrates MP2 is superior. P.S. I do not work for Marantz.
