I've had 100% good results buying optics from CameralandNY, Natchezss, Amazon, and Optics Planet.
I know I'm not alone with my experiences with Optics Planet. They are notorious for showing items in stock, then sending an email after the order has been placed informing that the item is not in stock and that shipment will be delayed as result.
