Thank you Scott. The Edirol is a sweet device. I could wish it were CF based rather than SD since I have oodles of CF but no SD. On the other hand, for audio, 1Gb would last me forever (and I can dump it to my portable HD)

Internal mics are fine. 24 bit is probably more than I need, but hey, why not?

I'm not an audiophile, but I want something that can capture some depth in a recording of a dawn chorus, for example.
