Several of you have asked me about a good quality, digital field recorder for audio. I’d recommend the Samson Zoom H4 Handy Digital Recorder. It is very mobile, and you can attached a wireless mic to it if you like. It is available from a variety of sources, including Sam Ash and Zzounds, for around $300.
If you’re looking for a decent stationary USB condenser mic, try the Samson C01U USB condenser mic.
