As subject says, I'm looking for an (older) '700 or '800 model. I don't know why, but the AA battery seems to last longer on this than as a "side car" on the '900 model. Does anyone know why? Anyway, if you have a 700 or 800, please send me Email, to richard (my first name), at the site, soundmann.com. Feel free to drop by to Http://Soundmann.com for a bunch of recordings too. Richard
