A Simple and Easy Google Map Plugin

I am placing Google maps in my pages using code similar to below. But I have to go into the html on each page and change the address I want to display (three times in the code below). Does anyone know of a SIMPLE plugin that will provide this functionality and only require me to put in an address ONCE? I have perused the plugins, but they are cryptic, require a license, etc. Here is what I am using now. Arghh! Thanks for any help.
