My budget is around $100 but the cheaper the better. Any suggestions besides DIY?
get the king of fighters 2000 special ed nuby stick.
the sf anniversary stick is under 100 dollars, is pretty ok stock, and becomes fantastic with a little work.
i just can’t figure out where the hell to buy any of these sticks. 
Ask DreamTR in trading post, he has a few SFAC sticks on sale it seems.
