We purchased an H2 for my son to do prescreening recordings (he was making them at school); we also have used a snowball mic, which simply plugs into a usb port on the mac ibook or whatever and records directly onto the computer. Son has used the H2 for several recordings (cello+accompanist) and thinks it's better quality than the Snowball. We purchased it from a cellist who sells several different "portable recording solutions,"
Portable recording solutions. WingfieldAudio.com.. My son's teacher has had an Edirol recorder for more than a year, similar but more expensive than the H2; both do great recording.
Don't yet know if his H2 prescreen recording got him a live audition...
