Recommended PS2 -> XBOX 360 converter?


I bought a PS2 custom stick a while back, and recently got a 360 + SFIV. What is the best bang for my buck converter out at the moment? I searched and didn’t come up with much useful information, and spoke to a friend about it who said they all cost upwards of $100.

EDIT: Ignore this; I finally got the topic to come up with the info. Thanks!
