we have found the company that is reasonably priced and I have added a link here for you guys to look at I'm not saying that it is the world's best stuff but were willing to give them a shot all I know is it's a hell of a lot cheaper than most the companies and I believe it's probably the same stuff as you probably know all pigments are about the same all they do is add color to them say like fluorescent or something like that I thought you guys would appreciate this link also.
