I've hesitated for a while to provide a link to the Implant Nation web site, because when I've visited it before, it's been broken: a home page with links that promise more information but turn out to go nowhere.
I'm happy to say that it looks like the site is undergoing renovation. The links go to pages that clearly aren't yet finished... but at least they go to pages that exist. I look forward to the site's completion. Implant Nation has raised the bar considerably for prim breast capabilities and user interface, and it deserves a good web site.
