I've been using Chinese screens off ebay for the longest time now. Its theft how the ones on the sub site are sold for $1 each. Anyways these normally take quite awhile to arrive but I believe it is worth it in the end. http://www.ebay.com/itm/50-1-2-Heav...338130?hash=item3ce3a5e612:g:eawAAOSwo8hTraYw Ill usually buy like 10-15 packs of them and they last me over a year. They are sometimes annoying to get in but they fit well once you poke them in to be secure. Hope that helps, my screens clog once every few days I vape so much, can't afford a dollar a screen, lol.
