Its fine to get extra stuff on your ticket, but be careful when you apply to an airline. I had friends who where CFI, CFII, MEI, AGI,IGI, Gold Seal,etc... and listed all this stuff on resumes when they applied to an airline. I have all the CFI ratings but chose not to pay for the extra test since I thaught it would be useless. In their particular case the interviewer started asking them all sorts of questions about fundemantals of instructing,etc... and since they had not studied the stuff for two years they did not remember any of it. If you are a career CFI it makes you look good to students who think you are better than the guy without it. In an airline interview it might look like you are padding your resume, since they know you only have to take the same test twice to get it. Now I'm not saying this will happen to everyone but be careful waving that goldseal around.
