Josh & his buddy recently introduced me to the Zoom H2. The last thing I need is another piece of recording equipment, but I have to tell you - man, I'm really tempted.
This little thing is just ridiculously cool. it is smaller than a pack of smokes, it records in stereo or ambient 4 channel, it stores to SD cards, it runs on AA batteries, it's bottom is threaded to attach to mic or camera stand, and it is braindead simple to operate. Oh, and it does everything from web-quality MP3 up to 24/96 4 channel output - and evidently some enthusiasts have written a program that takes its output and mixes it to 5.1 channel so you could basically use this thing to record the audio portion of a 5.1 DVD of your band if you're a bit tech savvy. OH... and it has a built in metronome and guitar tuner... and it's friggin cheap... and it sounds good.
I searched around and found a good review on it: http://digitalmedia.oreilly.com/pub/a/o ... tml?page=1

You get one chance to enjoy this day, but if you're doing it right, that's enough.
