Hi,
I'm interested in recording myself playing piano, both for improving my playing and (eventually) for sharing with others on the internet to receive some constructive criticism. Can anyone recommend an inexpensive setup to do this that is good enough so that I will be satisfied with the results? I'm currently planning on recording to my portable MiniDisc player, but it only has line in and not microphone. So in addition to a microphone I learned I need a preamplifier.

And I'm clueless about what type of microphone to buy. If anyone has done research for their own setup, I'd appreciate hearing about it.
Any suggestions would be appreciated, Chris Mejia
