I'm mostly recording music where I've got things set up in advance vs needing to quickly capture something on the fly but I've liked the Zoom H1n, Sony PCM-D100, and Sony PCM-A10
I can see that these are indeed targetting musicians and are way more sophisticated instruments than what I'm looking for. I'm still grateful for the info!
I picked that one up while traveling and I'm surprised at how good that little guy ended up being. It's lightweight and even without an external mic holds up pretty well. It's the one I tend to grab when I just want to record a melody or a few chords.
I'm thinking about getting a cheap tiny dictaphone for logging ideas daytime for distilling them to my notebook/journal when at my desk.
ps: I find phone apps too cumbersome to get to the point where the record is running, by that time the idea might slip.
