Atomic Gamer is free, reliable, and gives you plenty of memory. I use it and have downloaded several mods from it, all without a problem. Somebody used to beg me to upload my mod somewhere else because he couldn't use Atomic Gamer, but I don't get why. Sure, there's a wait of a few minutes, but think about it. You are downloading a mod that took months to make and will spend days or weeks of free time playing it (or hours trying it depending on what you think of it). What's a few minutes? You can minimize it and do something else. Look at the reviews of other games (good for the juices really). The only problem is its so good and easy there's a danger of all the eggs in one basket.
