It isn't the app that costs, that is free, it is the data download you need a subscription for. The zap2it site (I will post the site stating this tonight) is supposed to be able to sync the data for free.
Here is one I found over at TreoCentral, I installed it, but it takes an act of congress to open, and does have limitations (only new episodes), I thought you guys would want to check it out (if you haven't seen it already):
