Mark Levin
He's basically taken the Savage Nation (which he calls the Weiner Nation) but put some intellectual context around his tirades. If you need a lift or need to vent, his opening monologues will get you going. His web site has the last 4 weeks or so of his podcasts, and they're free.
I shouldn't really enjoy hearing him refer to Michael Savage as "snaggletooth" or Senator Clinton as "her thighness" but I secretly do. I can at least say that he doesn't lampoon anyone undeserving.
So, I think this is a good change. Beck's show is well-produced, Glen is very talented, but the show seems somehow less than the sum of its parts. 10 pm is a better fit for him, IMO.
