Well after a long thinking process I decided get the YN-565EX, I just received it this past Tuesday and I currently tinkering with it. It is a big improvement over the $60 Walmart flash. Have taken a few pictures and still trying to get the hang of it and trying to make it work with the limited light in my apartment. I am also looking over all the links to get more information on how properly take pictures using flash.
