I mainly check out the podcasts from Austin, JR, Jericho, Flair & Tazz (also used to get Roddy's before they were removed from podcastone, are his old ones available anywhere now?) - particularly if it's their review of a PPV, or an interview with someone that particularly interest me.
Also get Chael Sonnen's when he interviews a rasslin' personality, used to listen to Colt Cabana's but haven't for a while now since I had some issues downloading from his site earlier in the year.
Will have to remember to look into Jim Cornette's, have liked the ones where he's been a guest (Flair, JR etc), so I'm sure his own ranting & raving should be interesting.
