Millennium Sports makes a good product called CREO2. I have taken it several times and can feel the difference in endurance, especially if I take it preworkout. I can't compare it to straight creatine monohydrate powder (for it has been years since I've taken that), but others I have talked to said it won't give you the bloated, puffy look like monohydrate.
While the CREO2 has some proprietary blends, the extra ingredients in there are great fillers.
