BitMeTV (or any of the others mentioned) for most everything you might want (at least all the current stuff). You might toss in RUTracker to get anything rare or difficult that the other doesn't have, but don't keep it on all the time as it is more risky (far less private). With all the Demonoid trouble, RUTracker seems to be the alternative. Use it like you might have used Demonoid (very sparingly).
