Hello, I'm a newbie and would like to buy a digital voice recorder mostly to record interviews and conferences. I didn't find an article in the Articles section about the top brands and models for DVRs. An article somewhere (NYTimes? Slate? Other?) on the Net last year recommended the Olympus DM-520, which is now end-of-lifed, and the Tascam DR-08, but mostly for recording live music. Recently, I saw someone at a conference recording with a Zoom H4n and he told me it was a great product for this. I have a couple of questions: 1. What top features should I check for when buying that type of equipment? 2. What brand + model would you recommend for personal use, ie. not expensive, professional gear? Thank you.
