I just purchased a unit by Sony which is easily kept in a shirt pocket with room to spare (Sony ICDPX312 Digital Voice Recorder). I don’t have much experience with it yet but a few test recordings yielded good results.
This one is a bit more pricey than others but I selected it because the files are saved as MP3 and can be uploaded via a USB cable using Windows Explorer. Many others use a proprietary format which requires their special software and I didn’t want to mess with this. Files can also be downloaded.
It also accepts a media card if the built in 20 plus hour time is not enough.
There is an input for using an external microphone as well.
In Ohio the law doesn’t prohibit “secret” recording of an in person conversation as long as one party is aware of it (usually interpreted as the one doing the recording). This wouldn’t apply to an interview but you should know your laws regarding this.
