I know there are LR 510 atties, but I want to know if any are made by joyetech. If not, which are the best? I see them on websites ranging from $5 to $10 each. Also, I noticed there are different manufacturing companies that make LR 510 atties. Has anyone had any good/bad experiences with a certain Lr510 atty manufacturing company? Please help and thanks in advance.
