D20 Modern has it's own podcast at long last, called Accidental Survivors. The podcast is hosted by Fraser Ronald of Sword's Edge Publishing. He was also the author of Blood and Guts II: In Her Majesty's Service, published by Sword's Edge to support our Blood and Guts II line.
The latest edition of his podcast is all about modern resources and has a great listing of PDF products and general information websites that will greatly enhance your modern game.
And of course, there's more than a few RPGObjects books mentioned, which is really flattering and just overall awesome.
