I suggest the ZOOM HD2 digital recorder that can also be used as a mic, it can store up to 17 mb of audio in stereo or 34mb mono, we use them for remote broadcasts to record our breaks and then email them back tot the studio for air making Marti's obsolete, plus if I want to get listner audio for imaging, I just unplug and walk around getting comments and they sound freaking great! It will run you about 200 bucks but you might find them on ebay or your favorite gear outpost for a little less. A few hoops to jump through but IMHO a great piece of gear for laptop broadcasts/recording.
Hope that helps
