I too have been an early 1UP Yours listener and IMHO its hard to beat Lee, Davison, MacDonald, Smith and Bettenhausen when it comes to a gaming podcast. But those days are long gone and I actually happen to like Weekend Confirmed and think that each member including Mr. Leahy brings their own certain "charm" to the table. I think if you like video and follow video game news at all, you should give WC a listen.
edit: I am not a fan of Rio's musical interludes or Garnett's choice in the music he uses in the song section. As for a fourth chair, I would love it if Mr. Davison was available.
