i know nothing about minidisk players/recorders and i need your help please. I want to buy a minidisk player/recorder to use for live interviews that will later be uploaded on my laptop and then burned to a cd. I need either it to have a mic or to have a jack so that a mic can be plugged into it. I shall need it to be able to record the voice as clearly as possible. I would like to have some sort of ability to edit while interviewing if possible, but the most important qualities are clarity of recording, mic use ,upload ability to a pc and durability for i shall be using it alot. Any help would be appreciated. The price range would be no more then $300.00. also if there is warranty that would be great! thanks for your anticipated help.
