I purchased the very same Sony minidisc walkman recorder a few weeks ago and was also delighted with the quality of the recording. I got a small stereo mike which can be clipped to your shirt and it works beautifully. The model is Sony MZ-R7OPC and it cost around $75.00. I've been clipping it to my collar and recording (playing guitar and singing) but I'm going to experiment with other setups. You can run it through an editing program (I use Cool Edit) to add a little reverb and it comes out beautifully, then you can burn it to a CD! I put some of my own songs along with some other's that I took off professionally recorded CD's and there really wasn't that much difference in the quality! I will be using it for field recordings in May and will report on how it works, but I have a friend who used it for this purpose and it was superb. What a great invention!
