Once upon a time,
www.redoctane.com was selling blanks for about that price.
Last year they had a closeout on xbox fighter CPs for $24...I picked up 4, used the xbox PCBs built in, replaced the joy and buttons with stuff from Happs, gave out as gifts to nephews and others, now the PCBs are one by one goin bad.
They don't appear to have any blanks for sale atm and their only fighter joy is PS2 for like $60 + ship.
I'm in the middle of replacing the xbox PCBs gone bad with RandyT's new keywhiz USB interfaces as soon as he gets the cables in......
Doesn't really answer your need but thought I would share.
