>>5810138WTF@TFW is decent. The usually-weekly podcast goes into most of the week's TF news, and they provide good insight on happenings in the Transformers sphere.
The roughly two-hour length might put you off; with the meager amount of news we get in an average week, they only really spend around 45 minutes per episode on that; the rest of the episode goes to listener questions that probe them about things that usually relate to TFs, and the last chunk goes to mini-reviews of the on- and off-topic toys tat the hosts get on that given week.
The show is hosted mainly by Vangelus (the Youtube toy reviewer), with one or two cohosts depending on the week. The guys who aren't Vangelus don't really have radio voices, but it's usually worth hearing everyone's opinions on shit.
