After the most recent Lost episode "Flashes before your eyes" I called into the Lost Podcast with Jay and Jack and they put my call on the show. Check it out Here and you can check out their website here.
Jay and Jack do 2 podcasts a week, one right after each new episode where they do a rundown of the episode and play listener calls and then a recap show on the following monday. They do give out some spoiler type information, but usually give a good warning to skip ahead when they do. Give them a listen if you like the show Lost on ABC.
