I wish you did too, but read on.
I have the Creative Zen Nano circa early 2007, but it records for shit. With the built-in mic, it records something like 8kbps WAV, which is worthless for anything but speech (and even then, just barely). Don't bother. With an external mic it can theoretically record up to 160kbps, but it has no input level settings, and so it's almost impossible to avoid overloading it. I tried recording one acoustic, non-Morrissey show, and the 07/02 Wolf Trap Moz show. It wasn't horrible for the acoustic show, but the Wolf Trap recording was a joke.
My experiences recording Wolf Trap with an iPod + Griffin iTalk were recounted
elsewhere, and although it seemed to work better, the results were just as bad. Not only was the sound completely overloaded (and thus sounded like nothing but distortion), but the iTalk (and apparently most, if not all, recorders for the iPod) skips a couple seconds out of every 30-60 seconds of recording. You don't notice it at first, but it's absolutely intolerable. Don't bother.
For the 10/27 Hammerstein show, I took
robert's advice and bought a Samson Zoom H2 digital recorder, and the results were excellent.
Read and listen for yourself. I tried to get the recorder into the hands of members who were attending the 10/31 Baltimore and 11/02 DC shows, but I had to go out of town and missed the hand-offs. Lastly, I'd point out that the H2 costs $200, but...
I propose that the SoLow community buy a handful of these H2 recorders and lend them out to show attendees. Just imagine the possibilities.
