I picked up a Sanyo ICR-S170M digital voice recorder from Yodobashi Camera in Shinjuku and I am well impressed. My former voice recorder was a Sony model and while it looked beautiful the controls were counterintuitive and the use of the proprietary .MSV file format meant either running an emulator on my Mac (takes up space, slow) or extracting files to my work PC and then converting them to a Mac friendly .wav format. The ICR-S170M has no such problems - it records as mp3 and connects via a USB cable, so moving files onto my PowerBook is a simple drag-and-drop operation. I have been recording everything from formal speeches, workplace conversations, party talk and even my own weekly lessons - nothing like listening to yourself speak Japanese to know how good or bad you sound! Up to 8 hrs of recording time, depending on the recording quality selected. And the best part - only 12,000 yen!
