I haven't used SAS University, specifically (because I have access to a paid, licensed version at my program), but I've heard good things from people who have used it. You might want to look into it because it is free from SAS (at least in some cases). Any objections to using SAS University? I would imagine functionality might be slightly reduced from a full-paid version, but it's one heck of a program (so I can't imagine the free version totally lacking).
