What is the best cloning gel on amazon?

I only want to make 1 or 2 clones and I was planning on buying a small amount of cloning gel off amazon since I have a gift card. http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias=garden&field-keywords=clone+gel&x=0&y=0
I have never cloned before not sure what technique I will use.

Best is a hormone rooting POWDER.

Anyone have a great method? I've tried gel / powder / nothing and I have 0% success. I need a method that works.
