I have a laptop which appears to only have a mono microphone socket.

I was wondering if there is a cheap way to record two inputs at the same
time to two separate wav files.

For example, is there a piece of USB hardware that will allow me to plug two
microphones into it and record two separate wav files simultaneously?

Anything?

Any ideas/solutions/comments?

I'm looking for something cheap - the cheaper the better - but I'm accepting
any ideas whatsoever.
