I’ve used the Mobile Pre for several months. It will turn any computer with a USB port into a good recording machine as long as you have a decent mic. There are a lot of good ones like the ones listed above. But on the subject of mics, I bought an Audio Technica 897 – a short boom mic for my new camera — and I can’t believe how good it is. Of course it is more ($247) but a great mic for all uses.
