Kenneth, we do try to add links to suppliers when possible. In this particular review, clinking on the Iwata/Medea logo at the top will bring you to the manufacturers website, which many times will either sell the products or list vendors.
Past the summary box on the review page you'll see a 'thanks' to Airbrushes.com, this is the company that supplied the product for review and a link to their website is included there, also.
