Haven’t used this for podcasting...but the Zoom h6 is a great one for recording audio as a filmmaker. It uses a regular SD card, AA batteries, 4 XLR inputs with separate controls. We have them at my school and I love them, but again, I don’t have a portable podcast setup like what you’re looking for, so I’m not sure if this would work for you. It’s in Amazon for about $300 (ouch). Definitely take a peek though!
