I have to order a few of these for the college I work in to replace the Mini Disc recorders we currently use, well used to use until they got broken etc. I dont even know where to start, Any advice? Its not out of this world quality thats required or anything, will be used mostly for speech recordings, ability to record as AIFF might be a bonus as well, if anyone has any pointers on where I should be looking that would be much appreciated
