We use a sony minidisc recorder/player with a single stereo condensor mike and dump through the computer for play on the ipod and car stereo or CDs.
We record in the field at festivals. Best results seem to come from placing the mike on a mike stand in the midst of the session and aimed horizontally, or suspended from over head if here's less ambient noise (never happens at Galax).
The recordings are excellent in quality and have a 'being there' quality that studio recordings, mixed with ProTools,etc., lack.

cheers,
