hmm, i have been thinking about doing the same thing.. just another thing to add to that golden document.

as far as i saw they are around $125 US to sit the exams.

but similar to what Arto is saying.. if i were to do it.. and then my certificcate expires.. surely an employer would still accept it? or do they like them being up to date.. i ask since i don't plan to look for work.. but if this helped as a backup plan, it'd be worthwhile.
