If you want the DLC, you probably have gotten your money out of the main release and then some. I remember being a bit put off by a Left4Dead 2 release, and then realized I had put 500 hours into the previous one @ $.10/hr. That's cheap entertainment. I'd rather buy a game at a low price, and then get nickle and dimed after that, because at least then I know it's worth it. Some games you buy and immediately realize it was a mistake (like Dead Space for me). That's the situation to avoid.
