Be careful if you are buying a new product from TeleVue.
From what I understand ALL products that had Set-Screws now have the new Compression Fitting installed. (prevents the marks on the ep). The only part that will keep the Set Screw for a while is the Erecting Prism.
Make sure if you are getting a new Barlow or anything else, that you first ask to make sure you are getting new stock. Make sure the part has the Compression Fitting!
