My rankings (active podcasts):
Coast 2 Coast - love the frequency of new material and opinions
Pinball Podcast - love the humor and how it is all about pinball
Gameroom Junkies - these guys are great, but I can't get into the vid stuff too much
Pinball Soul - great stuff, love the recent interviews. only knock on it is the lack of personal opinions on games, etc.
Spooky - sometimes i feel like only 10% of the show is actual pinball stuff. I skip the EM dungeon.
