$35.00 from TritonLabs

...or $160.00 for an installers 5 pack. Either way, yeah, its making the $59 GBA around $100... but at least you are helping the little guy out, rather than throwing more and more cash at those Mario-Lovin', Mushroom-Eatin', Nanking Rapin', Japanese Business Hoodlums. Check out TritonLabs.
