A new online ultrasonics components store has just opened at www.UltrasonicsWorld.com. Check their amazing prices for replacement ultrasonics components, fully compatible with the major manufacturers' originals at a fraction of the cost.
I've just updated the website to version 6 of Drupal's excellent content management system. In the process I've also made some changes, particularly in the way that thesis downloads are provided. If you have any questions about this or find any issues on the new website, please let me know through the contact form.
