Many of my current templates are not compatible with PS Elements. I use a single PSD method that requires the use of several features that aren't available in Elements.
I can create an Elements package for almost any of my previous templates. These range in price from $25-$75 depending on the complexity of the template and whether I need to create a new set of files especially for you. If you have your heart set on a template that is not Elements-friendly, I can generally get an Elements package ready for you in just a few days. :)
Here is a current list (as of November 2013) of Elements-friendly templates:
