There is a lot of 3k3y version, for your purpose just find one that supports 2000x and 2100x.
I can't seem to find one that explicitly says 2000x or 2100x... Modchip Direct actually says it doesn't support them, despite being SATA.
Can you link me to one that supports the 2100x that ships to America? If it's against forum rules I understand, but I don't see why it would be.
