I've ordered a c64/amiga/atari joystick adapter from retrousb.com, but I have received nothing, and get no response by email. Did anyone else here order anything from that store? Do you have ideas about other places to buy an adapter?

EDIT: Items finally delivered, and works perfectly. The customer service was extremely slow but very nice when I got in contact, finally. They even offered a refund if the items could not be found.
