But what qualitative difference is there? I don't really need a lot of features. I just need something that's easy to turn on and start recording and that will be reliable. I have been using an Olympus that records in WMA format and has worked fairly well, but is cutting off automatically for some reason. So I need something slightly better quality. I have looked at all of the recorders by Tascam and Zoom and I really can't tell much difference between the entry-level model and the more expensive models, except for additional features that may not be useful to different users. So really, what I'm asking is, is a lower end model sufficient if I don't need special effects, or a better microphone, or whatever else distinguishes a much more expensive model from a cheaper one?
