3b-D-Verb is included with Digi 001 and ToolBox PT LE systems. If you are using Pro Tools Free, a demo version is included on the PT Free CD, or if you only have the downloaded version of PT Free, you could try downloading the demo version from the Products/All Products Index/Software section of the website. (I'm not sure if that demo works with PT Free, but give it a shot)
A special version of D-Verb RTAS for Pro Tools Free is available for purchase in the
DigiStore for $49.95.
