It's on my to-do list, but the arcade hardware itself can get quite pricy. I may end up just using USB controllers instead of the buttons, sticks, and trackballs.
I'm throwing in another vote for Pocket Casts. Bought it back in 2015 and the web player as a separate purchase. It's had ups and downs over the years, but I've always returned on the rare occasions I tried something different in hopes of finding something better--granted I'm grandfathered into premium at this point. It ticks all the boxes for me and I'd probably buy it again if I didn't already have it.
