I have been using a Tascam DR-05 for many, many years now to record rehearsals. Amazing little unit. Runs forever on batteries. The mics can take a ton of SPL punishment and hold up well enough to study the recording after the fact. Runs on a cheapy SD card. UI is meh. But it's mostly set-it-and-forget-it.
I'd recommend one over a video device. I don't see the value in video unless you need it for a social media channel.
