Here is a link to a site that has the Optivisor as cheap as I have seen it...less than 28 bucks. They also have the Opti-loop accessory which I have on my visor and like it very much for that really close up stuff. http://www.misterart.com/store/view/001/group_id/8142/Donegan-OptiVisor.htm Stan Rife W5EWA Houston, TX K2 S/N 4216
