I tried cafelatex too because I wanted to "try something different other than Stans."

Poor choice.

Punctured the center of the tread on an urban, cafelatex speweed everywhere - all over my bike and my legs. I still, to this day, cannot remove most of the dried crap from my Niner... PISSED me off!

Stan's. There is no other sealant.

...although, I've heard of some homebrew that's worked really well. Bruce @ HH has a recipe he may share if you're interested.
