Best Audio Recorders

Planning to record your classroom lectures?  Here are the specific features to look for:

• Microphone Sensitivity - Unfortunately, the built-in microphones on many inexpensive audio recorders are only meant for voices a few feet away from the device.  But you may not always have the luxury of putting your recorder anywhere near the front row in a lecture hall.  Or, the front row may be a long way from where the teacher is standing.  You'll definitely want a recorder with a sensitive microphone.
• (Optional) Bookmarking - Some recorders have a Bookmarking feature that lets you instantly come back to a particular spot in the middle of a recording.  This can be particularly helpful when your instructor says things like, "This question WILL be on the test!"
