Hello, I have a basic question: I have recently become interested in getting a portable digital recorder. My main uses would be in speeches, conferences, and one-to-one interviews. All of this for personal use, and occasionally for web posting. I would be tempted to record live shows too, for the same purposes as above. I have looked at the top olympus offerings, the LS-10 and the DS-71. I want to know if getting a more basic recorder (Sanyo S003M ~$100, only records MP3's up to 192) with an external microphone would give me comparable sound quality to those recorders. Thanks for any help you can provide.
