According to the MD community's data page on the MZ-NH1 that looks like a very fine machine and not a bad price either. Sort of thing I'd get if my MZ-R30 ever breaks. I particularly like that it has a mic sensitivity switch, a feature that was dropped from many recent models. I always use it in the less sensitive position and the auto level control rarely kicks in

The Sony mic isn't bad, but you can buy a small electret mic for less than £30 in cheap electronics shops, and they work well enough for most purposes - i.e. surprisingly good sound. If I really wanted much better I wouldn't be using minidisc!
