Hello Richard and welcome to the Cow Audio Forum,
You don't give us much detail on what you're using to achieve sound that you don't like or why you don't like it. I think that needs to addressed before considering a recorder.
Capturing good audio is a craft as much as focus pulling, videography or plumbing. I could have en entire plumbing truck at my disposal and the results would be underwhelming.
You don't mention a mixer. The right mixer between the mics and camera (or recorder) is a wonderful thing.
Perhaps you could elaborate on what you don't like about your sound now and what your gear setup is.
Regards,
