Big Smooth

Hi, I'm new to this board. For the last 3 years I've been contemplating buying a portable MD recorder/player and have explored both Sharp and Sony models. Well, now I'm actually planning on buying one within the next month or so and would like some suggestions/information from all you 'seasoned' vets of MDs. Here is what I am looking for: 1)ability to record mp3s off the internet 2)ability to make quality field recordings(nature, trains, etc) 3)ability to make quality live recordings of concerts(mic level control would be a necessity) My favorite music is experimental, ambient techno, idm, jazz, and some folk. I welcome any information or suggestions on what models would meet my needs. My budget is no more than $250 us. Thanks! Mark
