In short, Les, you pretty much get what you pay for. The H2 is pretty much standard (the reason why the H4 costs more is that it features a host of pointless extras, but we'll pass on that). Never used the Olympus WS110, but they're a digital dictaphone basically; good for note-taking, but your not going to get anything like the quality of recording you get off the Zooms. Download my Durham Gala recording above (features a spirited take on Geordie Had the Bairn) and see what I mean.

Hope to see you on the first Wednesday sing in March - if so, I'll fetch along the H4 and record as much as I can.
